Nice looking tank, but I feel you have stocked it in a way that will in
all probability cause you many headaches, fair enough, people do mix
cichlids (I'm guilty of that), but the mozzies, and dempsies aren't really
suitable for a community tank (one too big, the other too aggressive.) I
presume by blue eye cichlids you mean what call jade eyes (Cichlasoma
spilurum), if so they will breed like rabbits and when they do they get
very territorial, I had a 2" female that would keep a full grown red belly
pirhana cowering in a corner (yes, I had breeding cichlids in with a
pirhana).

Back to your original question, ragged edges on the fins, and an upset
balance says bacterial infection to me, I would suggest a course of
treatment with a general bactericide, the Esha range always work well for
me, very tank friendly but effective.


Thanks for your comments, Dave.

The tank mates all started out as new small fish together. The JDs keep to
themselves - playing and chasing often, but they don't bother any of the
other fish at all! I've also traded off all but one of the Blue Eyes
(Cichlasoma spilurum)and that one is a runt. I did move my pair of
Convicts to their own tank as they will attack my hand when doing tank
cleaning! They would keep all the inhabitants of the big tank cowering in
one end while they tended to their babies...
Would Malachite Green be a suitable treatment for him?
Thanks,
Rob

Malchite is a parasite treatment, better off using Myxazin or as I said
before Esha 2000.
Cheers
