I purchased 1 ea juvenile synspilum, bleekeri, Frontosa, Gold severum and Cuban cichlid to grow together and hopefully keep together in a 150g. Immediately the Cuban was very aggressive and bullying. It targeted the bleekeri and I eventually removed Cuban and put into established tank with...

Hi all, So, the first three days the Firemouth just followed the Green Terror with no chasing of anytime, he seemed quite scared really. But it's been two more and he will not stop terrorizing him, just constant chasing. Is it supposed to be fun for them? My first time owning Cichlids and...

Hello MFK! I've come with rather exciting news - my keyhole cichlids recently laid eggs! I have six keyhole cichlids in a 90-gallon alongside a leopard ctenopoma. I've had all of them since late summer, and recently two of them laid eggs! It's the first time any of them have done so, however...

Hi I am in need of some help. I have an aggressive blood parrot, 7 in female. She won't stop harassing a red peacock cichlid I have. There is a 5 inch black convict in the tank, yes I know about the pH differences and it's a bad idea and stuff but they do completely fine together. The blood...
