I am sure many of you have a lot of experience with different fish species, lets share them via a tier list.
Rules:
Here is mine:

Fish: celestial pearl danio
advantages: beautiful; peaceful; ideal size for planted aquarium, not too difficult to breed (one fry has even managed to survive with other fish and grow up)
disadvantages: tends to be a bit shy; espensive
Fish: lemon tetra
advantages: their beautiful neon/yellow color is spectacular; nice schooling behaviour; peaceful - do not bother shrimp even if this is bigger than many fish who do; very hardy; cheap
disadvantages: might be a bit too big in some aquariums
Fish: pearl gourami
advantages: the most beautiful big fish that doesnt bother plants nor shrimp (mine are only 6 months old so not fully grown up, hopefully they will stay this way); unique characteristic of the "moustache"; cheap
disadvantages: sometimes showing aggression and chasing other pearl gouramis
Fish: kubotai rasbora
advantages: beautiful color; ideal size for planted tank
disadvantages: expensive
Fish: otocinclus
advantages: very peaceful; unique behavior (tends to sit on my echinodorus leaves in the same spot for multiple hours)
disadvantages: shy; fragile; might have difficulty with getting enough food; they should have a school of at least 6 which is even more difficult in terms of enough nutrition in smaller tanks
Fish: ember tetra
advantages: beautiful color that popup against plants; very peaceful; ideal size for planted tank
disadvantages: not very hardy - seems like they dont tolerate larger amounts of CO2 well
Fish: rosy tetra
advantages: a bit less flashy cousin of lemon tetra - but still beautiful; unique characteristic - "indian feather" on their head
; very very hardy; a school of these very nicely complements a school of lemon tetras; cheap
disadvantages:
Fish: espei rasbora
advantages: extremely hardy - the hardiest fish I had till now; nice orange color pops up in planted tank; cheap
disadvantages: a bit larger than typical rasbora - more like small tetra size; not as flashy as some other fish
Fish: kuhli loach
advantages: unique characteristic - more like a snake than fish; very peaceful
disadvantages: varying hardiness; escape artists; tend to hide almost all the time
Fish: betta fish
advantages: beautiful colors and fins; lots of variety; unique personality
disadvantages: fragile; requires warmer water than other fish; slow swimmer - might not get enough food because the other fish outswim them; some tend to eat shrimp; difficult personality
Fish: gold molly
advantages: tend to eat algae that no other fish touch - the green slimy stuff in front of substrate behind the front glass
disadvantages: tend to damage delicate plant leaves - rotalas for example; require hard water
Fish: neon tetra
advantages: flashy colors; very cheap
disadvantages: attacks shrimp; looking at their bodies closely some of them are very ugly - probably because of the large amount of breeding
Fish: corydora aeneus
advantages: peaceful; unique personality; very cute
disadvantages: they tend to uproot new plants as they scavenge for food - perhaps a smaller species is more suitable in planted tank
Fish: keyhole cichlid
advantages: very cute; unique personality - laying eggs and defending the nest; cheap, one of few larger fish that do not destroy plants
disadvantages: unfortunately they uproot plants that do not have roots established - replanting fresh tops or introducing new plants is a nightmare with them
Fish: danio choprae
advantages: nice color; unique - very active swimmer
disadvantages: their activeness cause other fish to stress
Fish: serpae tetra
advantages: nice red colors; cheap
disadvantages: very weird behavior - they do not school at all; very agressive fin nippers
Rules:
- Use Create a Single-Use Tier List (Private Tier List)
- 6 categories - S(perfect for planted tanks) till F(not suitable in planted tanks)
- Rate the fish primarily by suitability for planted tanks, then by anything you consider important (beauty, aggressiveness, cost, ...)
- Post advantages, disadvantages, general observations under your list to describe why it is in the selected tier
