Hey all!! It's been a while, but I'm concerned for my neighbors fish. It's a full grown marlbed angelfish in a 25 gallon tank. And note that this tank is regular, not tall. I was wondering if she's ok because she's acting fine, but I'm just wondering if she feels a bit cramped. My friend wants me to take her and I'm fine with that. I just want to know if I might have to get a new tank. Sorry, but I don't have pictures.
