I have a 55gal lots of slate caves, flowerpots and plants for everyone to hide if needed. I've got a 6in RD, 6in JD, 3in tiger Oscar, 3in GT, 2in JD, 2in flowerhorn, 2in Texas, 1.5in jag. I know these fish will eventually outgrow this tank and they will be moved. I have another 55,29 to get ready a ready 29. Looking for a 180. But they get along great in this tank. No real fighting going on other than the normal chasing. It's definitely the RD's tank though. My question is how big will these fish get in a 55though without stunting them?
