"Hoplisoma sp. aff concolor Rio Tomo CW217
Sensational is the import of this beautiful new [HASH=101]#Hoplisoma[/HASH]. According to the supplier, it comes from a small tributary of the Rio [HASH=102]#Tomo[/HASH] in eastern [HASH=103]#Colombia[/HASH]. The fishermen refer to this flow as the Cano Negro. The water is described as "crystal clear". The Rio Tomo itself is a tributary of the Orinoko. In Cano Negro, [HASH=104]#CW217[/HASH] is the only tank wave, there is no H there. concolor. "Here, a ""Thank You"" to our suppliers for this information!"
Undoubtedly, the new Hoplisoma "Rio Tomo" is a close relative of Hoplisoma concolor (see Welcome to the website of Aquarium Glaser - Aquarium Glaser GmbH Ian Fuller ( www.corydorasworld.com ) gave code number CW217 to this color striking fish. It should be noted that despite physical compatibility between CW217 and H. never concolor between "normal" H. concolor such dyed fish appear. So CW217 is not a color variant in the usual sense, because color variants are always found in populations of normally colored animals. According to most common species concepts, the CW217 would be seen as a subspecies (i.e. geographically isolated population of a species, which is constant in its characteristics) or - according to the so-called phylogentic species concept - as an independent species.
It is hoped that the breeding of the magnificent fish will go well. The virgin fish coloring would also provide important clues about the species. We know about other twin species (e.g. osteogaster rabauti and O. zygata) that they are only difficult to distinguish as adult animals, but young animals look completely different. For the time being, CW217 is only rarely and available in small quantities as game catch. The genders are pretty easy to distinguish. Males have long, pointed belly fins, the females on the other hand are relatively short and rounded. In addition, males often develop long dorsal fins (which unfortunately does not mean that all animals with short dorsal fin are females). All pictures in this post show the same pair from our first import. We were just able to import some specimens again and will deliver more pictures as soon as possible.

The new Hoplisoma “Rio Tomo” is undoubtedly a close relative of Hoplisoma concolor (see Hoplisoma concolor - Aquarium Glaser GmbH). Ian Fuller (www.corydorasworld.com) assigned the code number CW217 to this strikingly colored fish. It should be noted that despite the physical similarity between CW217 and H. concolor, fish with this coloration never occur among “normal” H. concolor. CW217 is therefore not a color variant in the usual sense, as color variants are always found sporadically in populations of normally colored animals. According to most common species concepts, CW217 would be considered a subspecies (i.e., a geographically isolated population of a species that is, however, consistent in its characteristics) or, according to the so-called phylogenetic species concept, a separate species.
It is hoped that breeding these magnificent fish will be successful. The coloration of the young fish would also provide important clues as to their species affiliation. We know from other twin species (e.g., Osteogaster rabauti and O. zygata) that they are difficult to distinguish as adults, but that the young look completely different. For the time being, however, CW217 is only rarely available as a wild catch and in small numbers. The sexes are quite easy to distinguish. Males have long, pointed pelvic fins, while those of females are comparatively short and rounded. In addition, males often develop long dorsal fins (which, unfortunately, does not mean that all fish with short dorsal fins are females).

One of the reasons I am posting this is because I first saw/heard about this species on either Friday or Saturday, 10/24/25 - 10/25/25. Well come to find out 2 of 3 first people importing these to the States I know and I was able to pre-order a group of them. I could not be more excited. I have seen a video of them as well.

When I was walking around Aquashella Chicago, I crossed paths multiple times with Logan Rando while he was filming. I was wondering if he had posted a video of the show yet so I checked out his channel. No video of Chicago yet, so I instead watched his video of New Jersey. About half way through the video, Father Fish rolls by on his scooter and announces he'll be making an announcement that will destroy the tropical fish industry. LOL! I didn't know Father Fish was actually a speaker at Aquashella. Seems funny that a guy who preaches about not giving money to the aquarium industry was invited to speak. I figured WTH, I'll bite and go to his channel to see what the big news was. I couldn't bring myself to watch the whole thing, but I did scan through it and still don't know what the big Earth shattering news was. Just the same ole preachy stuff and I regret destroying the brain cells. I have to be more careful of that, as I'm older and can't afford to lose many more. I'm sure glad my path into this hobby was seeing the work of Takashi Amano, other knowledgeable aquascapers, and all the great folks in this community.

Journal Kwyet’s 60G Hillstream Tank
Sometime in Nov 2024, I bought a 60G Aqueon tank at the 50% off sale. I already had a 75 gallon stand and tank, but I wanted a shorter tank so I could look in over the top. The 75 gallon was relegated to the garage in case I want it again, and I painted the stand black. I also put black vinyl on the back.
My goal was to make a hillstream environment, based on the long-running tank of Rachel O’Leary. I had looked at other options like the river manifolds, but I liked Rachel’s better. I set it up with an fx6 filter, a horizontal spray bar on the left side, and 2nd modified spray bar situated vertically behind a corner Matten filter on the back right side. Glass strips were attached with silicone to hold it. I cut the Matten filter horizontally a few inches from the tank floor so the top part could be easily removed for cleaning. I also cut a small vertical groove from the inside so it wouldn’t constrict the holes so much on the curve.
This was how it looked on Dec 20, 2024:

I'm looking to switch ferts I have a 20g low tech and 40g high tech both currently getting a mix of apt 1 and 3. I'm wanting to switch to pps pro using the gla salts (cheaper and gets my foot in the door with the dry ferts) for both tanks, but I've seen some recommend against it for low tech, I have no issues dosing daily, actually prefer it, and if I understand correctly, its actually better for the tank as far as stable nutrient levels. My question is, can this be done? Is it really that much of an issue to go pps pro on a low tech? I really want 1 solution (i.e. macro micro mixes) for both problems (the two tanks (obviously they'll need their own amounts as for as dose size)). I'm limited to 20 gallons of clean water at a time (remineralized with apt sky plus to 6 GH since I have neos, amanos and snails) due to space constraints so I can either do weekly 25% changes on the tanks or 50% changes every other week. Any and all input is welcome. TIA

I mention this plant on occasion, but no one ever comments. So I thought I'd make a post for others and me for future reference.
It is my favorite Erio. It is a darker green, doesn't get too big, and for me it has never sent up any seed stalks.
I find it easy to grow. I have high light but nothing crazy at 124PAR and high CO2, 50+ppm. It gets about max 3-4" and makes side daughter plants when large. I'm not sure my dosing scheme is. Sort of an EI daily dosing kind of thing.
What gets me is every autumn, it starts to melt. I'm not sure how it knows it's autumn with consistent light and a heater, but it must get a little cooler in the tank or something. The plant starts to turn brown and sends up (I'm not sure of the correct term) vegetative stalks with little plantlets on the ends. I've found you can plant these stalks into the substrate with the plantlet on top, and it will grow into a new plant. They've been easy to grow. This is the third year this has happened to me.
Pic of plantlets below. I'll try to get a better one sometime. All I had time for tonight was a crappy phone pic.
This year I divided one of the mother plants in hopes that it wouldn't fully melt and would regrow. That is still in progress.
Anyone else's experiences are welcome.
This plant is the same plant as the one on the right above.

Got on the tree build kick in past 2 weeks to make somthing I like for 36g freebie build to replace the huge tree turd #2 in there. I got 6 stumps ready today to get built for smaller tanks, 3 done today 3 waiting. Built the larger 17 tall 16 wide tree pics added other day to journal but gonna a build 2-3 more larger trees and the 6 smaller. Sell the ones off on eBay and etsy I don't want.
The larger stump 2nd post pic s 16" tall 15 wide plan to use in future scapes smaller. I've been using Amazon branch packs 15.00 for 25-35 pieces and amazon spiderwood 6-8" 5 for 12.00 for small trees. The large tree I made was a 10.99 piece I tore apart and used the 3 larger branches and built onto them to get the large tree in added pics cost me in end around 22.00 .... I have 10 pieces coming in mail Friday 5 large and 5 medium all spiderwood to make larger trees with this weekend.
Bought a ton of Amazon wood on Amazon lol 2 for 17.00 10-14" so I glued some of them together for larger usable pieces. some came out cool and well worth the 17.00 for the pieces glued together.The 1 has natural plant pots on top. The v shape last 2 pics 12" deep and 16" wide
After literally glueing a finger to a rock today Imao I quit! I ended up used all the accelerator I had anyway so Friday or sat before I can finish my smaller trees. will update as it goes, It will be a forest of trees when its done.

Has anyone ever kept Dwarf Neon Rainbows (Melanotaenia praecox) with goldfish?
I have 4 fancy goldfish (either Fantails, Orandas, or some sort of hybrid of the two). They are around 4–5 inches each. I also have a school of 8 Dwarf Neon Rainbows in another tank (2 males, 6 females).
The rainbows are super sensitive to CO₂. The moment I cross around 30 ppm in my planted tank, I can see them struggling, so I’m thinking of shifting them to the goldfish tank, which has no CO₂.
The goldfish tank is 300 litres (4 × 2 × 2 ft / 80 gallons), and the rainbows are around 1.5–1.75 inches.
Usually people say no to goldfish tank mates, mainly because of a mismatch in temperature or temperament. But in this case:

- The goldies cannot possibly eat the rainbows at their current size.
- The rainbows don’t fin nip, or at least I’ve never seen them do it.
- The water parameters in both tanks are quite similar.
- Goldfish tank: GH 6, KH 2
- Current rainbow tank: GH 4, KH 0
- Temperature is pretty much the same in both tanks: 24–25°C (74–77°F).
