Great idea when putting them in whole. In my case I had my hubby cut mine in half. I put them in the tank cut side down. My corys love'em. I have java ferns growing and covering up my tiny terracotta pots but it takes a lot of ferns to cover these bigger ones. By cutting them in half lengthwise they blend in better for me.The_fishy said:Insert a suction cup!
If you have really good ones that you trust, you could probably even insert one the other way and stick it to the wall.
I see, thanks for the explanation, I'll keep that in mind for my future tanks ^^awilkinson871 said:Many types of fish like caves and these work wonderfully. They are also used by shrimp to hide when molting.
