so i am having trouble understanding why my fish are dying slowly they are dying and nothing seems to be the matter i had just bought this tank from a friend (was already cycled) and set it up added atm's "colony" just to make sure it was cycled added Api stress coat and Api stress zyme.. over the past week slowly added fish in i have a bubble wall and a coloseum that bubbles. i made sure the levels in the new tank were the same as the old one!
the temp is at 86 ...(i thought i had an outbreak of ick last week so i slowly raised it and added API aquarium salt.. but it wasnt ick so im slowly trying to lower the tempurature)
according to api freshwater test kit my levels are
Nitrates: 5.0 ppm
here is a list of fishies that have died
2 tiger barbs
1 white cloud
2 neon tetras
here is a list of fishies in my tank as of now
3 albino tiger barbs
2 angel fish
6-8 zebra danios(they move to quickly to keep track)
7-8 white cloud
1 black tetra
these fish are in a 50 gallon tank and its a long one so lots of swim room...
plEASE help me find an answer.....
