I recently got mystery snails. They did excellent w out a heater. I recently put a heater in,one died. Now the other doesn't look happy. I moved her to cooler water n she's happy again. Do I not have a mystery snail?
I want to buy a product to make my own felt filters for various air pumps I own, what do you recommend? I'm asking about the kind used on the bottom of small pumps or the top of larger central air pumps.
