[swazley]

I'll try keep this short! I have a 100 liter tanks full of malawie's (26 ish) dirrerent ages and size. Iv'e had the tank for about 2 years now, simula fish same ammount last time round,8 monuths ago the one redtail shark went missing & i couldn't find it...tank went cloudy white & all the fish started flicking (spazin) 1 week they were all gone!! 2 fish servived but had blisters on them I treated the with "sterazin" as recomended. Fish recovered after a complete water, fish & gravel change. Tanks been settleled for now for nearly 4 month with no moer fish flicking or dieing. 1 of the seviving fish from the first setup got eaten today whisls at work. Iv'e pulled the malawie out but now all the fish are flicking again big time i've never seen fish flick like this! HELP PLEASE ALL COMMENTS WELCOME!!!!!!!!!!!

Your tanks sounds overstocked.
How many fish and which type.
Water stats in ammonia, nitrite, nitrate, and ph.

Water status is good in all areas ammonia, nitrate, nitrite, ph and water hardnes I have had a tank for roughly ten years but never had malawies or siclids. The fish are 20 different malawies 20-30mm, 2 convict siclids 50mm, three firebellies 60mm and two plecs 40mm. Two more died last night I aint got a clue what's going on!

It sounds very overstocked to me,, Are you running two filters.
Can you post your water stats please.
Any excess mucas on the body of the fish.
Check the gills for looking pale with excess mucas or red and inflamed.
Any gold dusting of fish. Turn tank lights out and shine a torch on fish for golden yellow spots, gold dusting, or a rusty coloured varnish.
Do fish have any grey patches with excess slime.
Any tiny white spots on the fish.

Sorry but i can't believe water quality is fine when the tank is horrendously overstocked with very incompatible fish.
Do you really mean 100Litres or 100Gallons? if it is 100L then the stocking is going beyond cruel.

You shouldn't mix american and african cichlids, firstly the water parameters they both require are completely opposite, secondly mbuna malawis are herbivores so should be fed veggie based foods and shouldn't be fed high protein foods like bloodworm which american cichlids should have. thirdly the two types should be housed in very different stuations, Malawis need overstocking to minimise aggression (although you have exceeded the overstocking suggestion by loads) American cichlids on the other need understocking to reduce aggression

a 100L tank is just big enough for 2 convicts or 2 Friremouths, It isn't big enough for any mbuna

For now turn up the temp to 30C, this will help ease off the Parasites, Also increase aeration

Parasites are always present in a tank but only attack the fish when they are stressed or ill, This is either when the fish are getting attacked or there is a water quality issue,

Can you post the actual water stats so we can just rule out this?

even in a 100G the convicts and Firemouths will not be compatible with mbuna, especially if any have 'paired'
