I have two right now I had them in a 75 and they didn’t do well then I moved them to my 240 and they took off eating really well swimming around they need a 125 gallon minimum you can mix them with severums ,peaceful Oscar’s ,starry night and jack Dempsey bigger tank is better
I keep my 3 widow frontosa with some mbuna and other tang cichlids they’ve always done well I can show videos always very deep colors on every fish but I understand what works for me may not for someone else
