Can you put these in a 29gal tank together.Lets say 2 kribs male and female.Then both bolivian and gbr's can be either all male or female.What do you think would work best.
Yeah, definitly not reccomended. Basides the already stated, these guys all like the lower levels of the tank and need seperate territories. Also when that pair starts to breed, they are going to start beating on everything else in the tank.
I could see all those fish in the saem tank if you had a lot bigger one like 95 gallon or bigger. Maybe not even then. So it's definetely not reccommended to put all those together, considering that they all occupy the bottom of the tank, as Vigro mentioned.
So I wouldn't plus the fact that you'd be mixxing SA and African fish together. Not a good combonation*thumbsdow
