Grow Out Tank

[chuckb330]

I currently have 4 Flachen Discus in a 30 gallon long tank. They are about 4.5" and just about 9 months old. Water changes are daily at 100%. I have noticed in the last month or slow they have seemed to slow down on growing. Should I get a bigger tank or continue what I am doing? Any advise would be great.

Thanks
Chuck

A bigger tank will help. Your tank is a good size for a breeding pair. A 55 should do it.
