I use a bowl for Plecos, especially my busy noses. Their bristles would be a mess in a net. They would get hurt for sure!
I am actually looking for a new home for my Sail Fin Pleco. He is BEAUTIFUL. I really hate to give him up, but I cannot supply the size tank he needs. He is in a 45 gallon, long right now. If you live in Southern California and are interested in my pleco, please let me know.
