Fish Sick Very Quickly

[WILDER]

Sorry bless him R.I.P.
What bugs are they?

 

[Amunet]

They're little gnats. Very small flying bugs. We always get them when it starts to warm up. I've been noticing a few bugs hovering around some of our tanks, but didn't realize that they had actually gotten into the filter of the 5gal.

Ok never heard of them as long as they don't harm the fish.
