MistersMom, I don't want to come across as rude, but I don't think you ideally should be giving stocking advice as your own tank is quite poorly stocked.
Mollies grow too big for a 10 gallon tank and do best in hard, brackish water. Glass catfish require a school so at least 6 individuals to be happier (with this species more is best) and as they grow to 8cm they are probably not going to have a lot of room to move about in a 10 gallon tank.
Here is a profile on glass catfish
