I think the 55 gal tank is big enough. My t-bar never bothered my cories. I think your other schools will learn to stay out of your t-bar's way. A 55 gal gives them plenty of room to do that. I added my t-bar last. When he was added (at approx 2 inches) my rainbows immediately started to school much tighter - cool to watch!Ok so the 55 will be big enough? If I had to add to my schools, could I put them in like a grow out tank until they're big enough or not? Also will the fully grown T-Bar (male) bother the fully grown harlequins or dwarf rainbows or even my corys?
You don't need a 65 gallon tank to house a t-bar cichlid with other fish IMO. If you have not yet purchased the 55 gal tank, another consideration would be a 40 gal breeder tank. That is another great size tank for a t-bar with other fish.Ok thanks? Someone else did say 65 gallon but my budget is around £300-£400 new or second hand. Should I stay at the lower end of this stocking list ie the 8 rather than the 10?
