Peppered Cory Cats not moving
 

Hi...

Yes I know I am comming off as a big worry wort... but I am.. so here goes.

today 2 of my 6 Cory Cats have been just lying in one spot for a very long type. They are alive, I can see them moving, but they are just lying there.

The other 4 are active as usual. All 6 are usually active.

I read on another site that the two not moving might be females, because they tend to lie in one spot on not move from time to time, but I am no expert and have no idea if this is true.

Today I added a small Canister filter (only rated for a 20 gallon, on my 29g) to back up my HOB filter, because I didn't think there was enough filtration or biological media.

im pretty sure they'll be fine. a couple of my 8 cories do that sometimes too. if something worsens then its time to post and see what people come up with

Its time to measure your water parameters. If you have any ammonia or nitrites it can affect fish in general and make them less active. I put a betta by himself into a new 45 gallon thinking that he would take forever to make the water deteriorate but I was wrong. A few days later he was almost looking like he was sleeping on the bottom of the tank. A little testing showed that I was starting to get some low levels of ammonia. I did a quick 50% water change and he came right out of it. He got put into a cycled tank shortly after that and is doing great but it reminded me of why we ae so careful about water quality.

oh BTW what all do you have in the 29???

Tank has

8 Albino X-Ray Tetra's
6 Peppered Cory Cats
