Bderick67;1506297; said:I think either tank would be fine up to about 16", with the 5x2x2 you could go longer up til about 22". What are the dimensions of your new 300g you are getting?
The 300 gallon will be 96x30x24, and I will attempt to do several peacock bass (cichla) with the jar. I'm planning on raising the jar with one other fish (maybe datnoid), and avoiding live food to keep aggression at bay. I have heard that by feeding an arowana a light-moderate diet it will grow much slower. I am on track to build a house in hopefully 2, but possibly 3 years so hopefully the tank will suffice until then.
