Tiger Barbs Died

[Swissgoalie35]

Hi,


I have a 46 gallon tank that had 8 tiger barbs and 1 rainbow shark and over the past few days all of the tiger barbs died off. They started out by not schooling and just hanging out at the bottom of the tank then one by one went to the top of the tank breathing very fast before dieing or being put to sleep by me. I do reg water changes and tanks water quality was all normal ( using the dip sticks)

Only the rainbow is left and even he doesnt seem normal. I want to try and save him I picked up a 10 gallon tank to use as a hospital but I would like to know why they died so I can learn from it. Ive had them since Septemeber with no problems until recently. I will attach a few pictures. Some have red spots and some did not.

You may wanna try getting an API freshwater test kit and double check all parameters. If they all were doing the same thing maybe they something?

That one picture, it looks like its gonna blow. What type of filtration do you have?

Just has the filter that came with the tank, the hang over the edge type

Yeah we call those an HOB(hang on back)

I'd get that test kit. There cheap online. The breathing heavy and sitting at the bottom isn't a good sign and IMO is a sign of water quality issues.

Sorry for late reply but the water was

Ph 6.5
Ammonia = 0
N2 = 0
N3 =0
Gh = 0
Kh = 0

I did a control by comparing it to my sink and the #s were similar. I used the api freshwater master test kit
