I am not sure what is going on here.
Tank: 29 gal, no detectable nitrites or ammonia (nitrate test is MIA), tank has been running for months (we switched around numerous tanks a month ago and then two weeks ago switched substrate and fish from two tanks, which included the 29 gal).
Fish: down to two female Mollies and 3 Celebes Rainbows (had 3 Mollies and 5 Celebes plus two replacements)
Last Wed morning, I saw that two Celebes had died overnight. We pulled them out, checked the bodies (fine) and checked the levels (fine). That evening, we went to the LFS and asked if he was having a problem with the Rainbows. Nope! The fish were replaced for free and I thought perhaps I hadn't fed them enough, since they were not wild about flake food. The next morning, everyone ate brine shrimp and I left for the weekend. On Sunday when I returned in the afternoon, I saw another Rainbow had died (body and water levels were fine). Before bed last night (around midnight), I checked the tank to find another dead one!!
This is getting annoying.
This evening, I noticed the water was murky, like a haze. It may have been this way for a while (a week or so). None of my other tanks look this way. My fiancé and I discussed pulling the filter (Fluval) and rinsing the media and water changing tomorrow (since it was 10 pm). Then I noticed a dead Molly. Again, no detectable ammonia or nitrite and the body looked fine. We did a 1/3 water change and pulled the filter. There is very little growing on the ceramic media, more bacteria was on the sponge. I thought that was odd since that Fluval had been on that tank since it housed our community fish back in January. The other odd/coincidental thing is the dead fish are all found in the same area of the tank.
Any idea as to what is wrong with my tank? All other tanks are fine, no losses and no cloudiness (including the tank I swapped fish and substrate two weeks ago).
BTW--this is supposed to be my brackish tank and there is some salt in there, but not much since I am waiting on the bumble bee gobies and wanted to acclimatize them all together, since all these fish were bought FW.
