I have an Oscar he/she is the only Cichlid I own atm. rarest I had where a breeding pair of Auratus at one point i think. I don't see those anymore like I use too.
My rarest is still my A. Rytisma and my Chuco Micropthalmus. I also have a pair Ivanacara Adeketa (Spelling) but I'm still keeping my fingers crossed with these. They never seem like there doing well but i still have them.
