Hi all,
I have never encountered an issue like this, but wanted to let you know if you keep anchor catfish. I found one actually stuck in a piece of driftwood. He had gone missing for a few days which is not unusual, but when tank cleaning I found his body solidly wedged in a crack in my driftwood- he really would have had to work hard to get in there. Specifically, his spines were stuck and it took some effort to get him out! I was astounded since I had him and the others in his group almost 2 years without any issues. I removed some wood pieces and child- proofed the ones I kept for the remaining catfish by stuffing filter sponge and more plants into the cracks. I just wanted anyone else who keeps this species to know they can get into spaces I would never have imagined.
