my malawi's are dieing off -HELP-

[arowana man]

i have(had) 11 mixed cichlids and one small sydontis euriptus. the cichlids are about 1'' maybe. my water peramiters are fine. the ph however is 7.5. low??? all three fish that died were laying on the bottom gasping for air. they eventually died. i feed 2 per day plankton, krill, and spinrula flake. the water temp is 80*. what the hell is going on.
-note- this is my first african cichlid tank

pH shouldnt be the probelm.

Stocklist? If there are mbuna, the krill could have gave them Malawi Bloat and killed them.

Filtration? Tank size?

40 breeder, one sponge filter with a Aquaclear 30 power head on it. its all i can do right now. here are some pics http://www.monsterfishkeepers.com/forums/showthread.php?t=102507 i dont know if there mbuna

 

[tarheels910]

Yes, all of your fish are mbuna. You are feeding them too much protein. Which probably killed them.

You are WAY underfiltered. You should invext in 2 Penuin 350s or something similar.

Cichlid gold, seaweed, Cichlid Excell, Formula Two, Spirulina Flakes, Cichlid Flakes. Basically any food that is for African Cichlids.

I feed mine this too. It is a good treat but should not be used as their whole diet.
