Neuro issue?

[LeClownBlanc]

My albino ACF has been acting oddly lately. As of today he's been swimming laps, diving in and out of water and when I went to hold him he was not resistant what so ever, which worries me.
He is in a 20 long with one tank mate who is doing fine. Temps are at 70 and I just recently did a water change.
I'm very worried any advice would do.

If you have a test kit, check for ammonia and nitrites. Sometimes the source water will have some ammonia or nitrites.

What substrate do you use?

I thought that and tested with the liquid kit. They both turned out normal. I use caribsea sunset gold sand and they have a marimo in the tank. Cecil seems to have calmed down. Maybe the water change freaked him out with the temp fluctuations?

Temp fluctuations don't normally cause such issues. pH fluctuations might.

We decided to change out the filter and do a partial water change. And see where that leaves us.
My cat also likes to harass the tank. Could my boy be stressed?

It's possible. Do you frogs have hiding placed in their tank?
