Hi. I am new here. I have a question about my danios. I have a 29 gallon with 6 glow danios, 2 neon tetras, 2 female bettas, a pleco, and 3 corys. I don't believe it is overstocked.
Everything has been fine in tank for about 6 months now. Suddenly, the danios have been acting strange. They swim fine, but they hold their gills very close to their bodies. Their backs seem to have a slight arch to it. On 2 of them, they are very thing although they are eating fine.
I haven't noticed the others acting this way, except on neon is a little pale, but the other is fine. The one was always a little paler. I was moving their decor today and noticed the carcass of what I believe was my 7th danio. This would have happened overnight, as I did a full tank gravel cleaning with their water change yesterday.
29 gallon acrylic tank. Weekly 25% water/gravel cleaning. 2 30 gallon filters running. All tests come out in very good range, no ammonia...etc. There was a little ammonia spike about 1 1/2 weeks ago when my one ghost shrimp keeled over on me and was inside a deco. Cleaned everything and it's been fine since.
What could this possible be? No other symptoms I can see.
