Pretty simple question. How many vieja melanura and maculicauda could you comfortably fit into a 220 gallon all male tank.? I was planning on getting a 300 gallon but might have to resort to a 220 but we will see.
1pair.
Fully grown melanura will soon fill that space.
If you want to do the crowded all male route,I don't think the tank is big enough.
Would a 300 gallon make much of a difference[QUOTE
It would help.
You could try ir and remove any trouble makers along the way.i think you would have a greater chance if succeeding if you stuck to one veija species and kept them in harems of 1 male and 3 or 4 females.
