i want to set up a nice little community maybe top and bottom swimmer with with the 2 male convicts. i have a bfish book that some what talks a bout leveling tanks with stock thought it might sound cool. for top swimmers 4-6 non fancy guppies or 3 sword tails (1 male 2 famales) middle swimmer 4-6 bleeding heart tetras bottom 2-3 convicts and 3-4 emerald catfish but i was thinking 2 bengal loaches. will this stock work in a 55?
