Hi, I have a 20 gallon standard tank with sand, loads of plants, and some driftwood. The fish tank has been running for almost 2 years and is maintained every two weeks, I feed my fish 2 times a day one at 12:00pm(afternoon) and another at around 10:00pm(Night) I have 6 serpae tetras(school), and 6 corydoras paleatus ( bottem feeders) and i have one baby balloon molly for a centerpiece fish. Currently the baby balloon molly is around half an inch, do you think i should mix the baby molly with the serpae tetras and the corydoras or not??? I am just a little worried the little guy will get eaten, and i have no other tank for the baby. Currently he has been in a little baby net inside the tank and he has outgrown it, i have also considered getting a fish tank divider, but i don't have the money for one. what are your opinions- Best Gage if you need more images just ask.
