I have had a female convict in my 55 gal and noticed yesterday she was laying eggs, so decided to get a male convict tonight to see what happens. I believe I got a male - it has a longer dorsal fin and is not as brillant in coloration. Anyway does it take a while for them to "hook up" - I put him in and is just getting chased by everyone right now (even female cichlid). Just wondering if there's anything to do, i've never had fish breed before.
