Malawi Bloat

Could be the brine srimp its normaly caused by protien. The wafers wouldnt have any protien in them.

What is the nitrate level? It is now known that high nitrates will cause this condition. All cichlids are susceptible to nitrates.

Food's with amimal protein's at more than 35 % fed too often to African's who are unable to digest it properly, often causes bloat.
African's would do better with food's such as New life Spectrum or Hikari Cichlid pellet's designed for these fish.
African's love the meaty food's but as mentioned,,they can't really processs it the way other larger cichlid's such as south american's do.
African's need a fair amount of herbivorous food's like algae based, or spirulina based, with only occasional meaty food's like fish,shrimp,salmon,krill,as treat maybe once a week.
Also help's to feed maybe once a day, as opposed to three or four times a day. IME

So are the foods that I listed high protein foods (mostly meat)?

As others have mentioned, it is likely feeding them the wrong type of food or feeding too much.

Cichlids will always appear hungry when in fact they are not which is dangerous as we tend to overfeed them. Their diet would be mainly good quality cichlid pellets, New Life Spectrum, supplemented with Brine shrimp, lettuce, peas (de-shelled), carrots (lightly cooked to soften them) and zucchini (they love and it is good for them).

You need to keep a very close eye on the fish if it is Bloat, full blown Bloat is 99% fatal to most cichlids unless it is treated very quickly. Give them a bit of Spirulina and feed them carrots, it will help.

You sometimes have to remove the bloated fish to a separate tank to fully treat them.
