Actually only about 1/3 of them have perfect fins. The rest are shredded due to aggression. But the larger specimens have some beautiful trailers.
The small fish are Golden Zebra Danios. I put in about 21 a couple nights ago and about 18 remain. One fish in particular spends the night hunting them at the surface. The other 13 are far less interested. I added the danios into the tank to try and get the frontosa used to other fish as I would like to add other Tanganyikan fish. The danios swim at the surface only, and are very agile and speddy. The one adament hunter strikes many times, and misses nearly just as many.
I only feed them live every couple months when I cull some excess male swordtails from the Sword colony.
They eat 3mm NLS. Though I won some Etreme-Exotics Cichlid Pellet on MFK for TOTM that I've started to use as my 5lb tup of NLS finally got low (after a year of feeding). The 5 pound tub of NLS was $55 and lasted about a year. Pretty awesome in my opinion.
