I've just gt a full setup from my friend about 3 week ago a 230ltr tank with a aquis 1050 filter , stone filter and heat tube , I had 3 diff types of bowmans rainbow fish in it they were pretty big the red 1 is 6 inch the gold was 6-7 n the other a think was blue was 7-8 inch , the 2 biggest have died n am worries the red is next , there was no obvious signs of wat caused it , am sure they're old fish but they were fine 1 minute then dead within hour any advice or help ?

Do you have a test kit to check the water? I think with moving the tank you may have had an ammonia spike, bosemani or infact any of the rainbow fish are quite delicate despite their size and do not like high nitrates or any ammonia or nitrite what so ever.

I don't have any testing kit av been meaning to get 1 , we transferre the fish seperate from tank with 80l of previous water , they didn't die straight away 1 died in the first week then the 2nd today the rest of the fish have been fine , clown loach , chinease loach, angelfish , red rums, gouramis , tetras , danios n dwarf gouramis I just put in on sat

My guess would be pH shock, ammonia poisoning would show early symptoms. You really do need a test kit, clean looking water is no indication of how good it is.

I will get testing kits ASAP , since the 2nd rainbow died last night my red rainbow has been awfy stressed swimming erratically round the tank then I found 1 of my tetras dead floating about tank in really worries about them now

Could I be under feeding them ? No matter how many times I feed them during day there all constantly eating it there is never any left lying on bottom after a minute

I don't think you are under feeding, you would be surprised at how much food a fish can find in an aquarium.

Okay I'll get the testing kits tonight what ones will I need ? Ph , ammonia

[Big Den]

Ammonia. Nitrite, Nitrate and pH, there are others but these are the important ones.

Okay ammonia is 0.02 on chart so it's well in green , ph is 7 n should b fine , nitrate n nitrite r fru roof nitrate was 110 n nitrite was 3.3 . I done a 20 percent water change straight away tank does look clearer any advice to help ? I lost another tetra today but just found out fish r 6-7 year old
