How about 3 pikeheads (Luciocephalus pulcher), 1 snakeskin gourami (Trichogaster pectoralis), 1 pearl gourami (T. leerii), and 5 zebra loaches (botia striata)?
Or, 3 hujetas, 3 sheep-pacu, 3 silver dollars or 3 golden dollars (mylosoma aureum), 3 bristlenose plecos, 5-6 skunk or bandit corydoras, and 1 glass knifefish (Eigenmannia virescens)?
Or 2 nandus nandus, 3 redtailed barbs, a peacock eel, and 2 sun cats?
I hope you are joking as 1 of these fish alone will get as long as a 55 except the bicher which could go in the 55. Now serious ly except the bicher or dwarf puffers the list is short. you need fish that will stay 7 inches or less for round body. 10 inches for streamlined fish. Exodons, belenosox,vampire tetras,chalceus,small cichlids like neetroplus nematopus,Amph. rhytismas, firemouths,convicts.
I suggest Poly. senegalus or Poly. mokelembembe, a Synodontis sp. catfish, Leopard Ctenopoma, and some congo tetras! Some nice anubias and driftwood...you got yourself a pretty sweet African biotope.
I have a 55gal and I'm almost 100% sure that's the type stocking list I'm going to get, unless I can find some dwarf channa
I did.
I do find it annoying when clowns give very bad advice to someone asking a real question.
A 55g is a nice tank but it's narrow footprint restricts the fish you can keep to mainly those that do not get bigger that 8-9" long. Everyone of the fish in Kuda's list will outgrow the tank in very short order. If Alphabg does get the rtc because he believed he was getting good advive then the people who gave that advice share the blame with him. He, for not doing more research, them for playing silly buggers.
Seriously, even a cute, 3" rtc will outgrow the 55g in less than 6 months.
Upyuns selection is nice though you might lose the occassional tetra to the ctenopoma as it gets to adult size.
