A 7 inch aquarium might be a little small, but a 7 foot tank would be good IMODo you guys think a 7" long aquarium would work?
3x kelberis will be fine in a 180g. Needs to be properly filtered and watch water perimeters and do water changes when necessary. I breed certain species of bass in 120's. 4x2x2. also watch for aggression issues.
not big tanks is always the answer. i kept 2 kelberis perfectly fine in a 90g even 120's just depends on the individual fish.540 min ,at least or more .....remember they look cool large tanks .......check out fish story's new post ......amazing 4500 gallon lol .......12x4x4 1400 is about right ....
