I have read that they are difficult, but I have had great success for the past year with new fish, so I thought I would give it a shot. The store had 2 of them but the other one was already starting to look weak, so I felt like this one had a much better chance of survival in my tank.
As for the collection of angels, thank you. I do love them, by far my favourite type of fish. Now I just need to get a larger tank so I can keep adding more and more of them. I am looking for larger tanks, but as I am in no rush, I am just waiting to find a good deal on one.
