I just got a 75 g and need to figure out what to do. I currently have a 55, two 45s and three 20gs. The only fish I have to get for my draft plan ore the giant danios and turquoise rainbow fish. This is what I’m thinking: 75 gallon will be a rainbowfish and cory tank Filtration - an aquaclear 110, an aquaclear 70 and 2 double sided sponge filters Stocking plan 14 preacox rainbow 12 forktail rainbows (not sure if this is ok for them) 12 panda cories (might get more or add my 5 albino cories) 3 Adolfo cories (can’t get more) Add 6 turquoise rainbow or another big rainbow 55 gallon will be a danio tank Filtration is two aquaclear 70s Plus two double sided sponge filters. Stocking plan: 12 long fin leopard danios 6 zebra danios 6 giant danios (have to get) 9 peppered cories 9 julli cories (not sure if the are real or false ones) This will allow me to get rid of a 45 and two 20 g. The 45 will be a tetra (diamond and candy cane), harlequin rasbora and cory tank. I have 12 neon tetras but they were stalking my cories and stealing their food so they are currently in a 20 and will probably stay there. Other fish eat the cory food but they don’t stalk and harass the cories.
