I have my three girls in one gallon critter keepers floating in my ten gallon tank for warmth temporarily and I really need to figure out a way to secure them so they won't too over.
The problem is, the lids on the critter keepers make it hard to clip them to the sides of the tank and I can't remove them because I don't want one of the girls jumping in with another one.
It was fine at first but I've decided I really need some way to keep them from tipping over. It's difficult to do water changes like it is now and I can only fill the tanks about 3/4 full because they still tip slightly, and 3/4 of a gallon is small and requires even more frequent water changes.
I was thinking about taking some sort of string across the bottom of the three critter keepers and attaching it to the sides of the tank so they have something to "sit" on if that makes sense? But I don't know what kind of string would be safe :/
