Tank size 6 ft x 2 ft x 2 ft (180 gal)
There will be other adult fish in the tank too but only one of each species or similar look.
I plan to put the labs in a 55 gallon until I can make sure I can pick out males. If they breed in the 55, it won't bother me since it doesn't have overflows. I'm just afraid that if I put a group of males in the 180 gal, they might not get along. Its a hard tank to remove fish from.
