2+ inches or medium sized pair. I've been having a hard time looking for a pair lately and i have been around a lot of fish pet stores already. I saw some at Petco but they were an inch small and some of them don't look good at all.
I have a pair of maroon's. The female is about 4 to 4 1/2" and the male about 2 to 2 1/2". I need to consolidate 2 tanks and they will have to go. Let me know if interested. And i can send you pictures.
