i know i have a thread like this and im sorry. in the ten gal i have 5 guppies (counting 1 baby) and i have 2 cories, 2 otos, and 3 mollies in the 15 gal, i would like to get some tetras and a betta somewhere but im not sure where. i think i should put the guppies in the 5 gall and over filter it then mollies in the ten gall ( overfilter) and leave the ottos and cories in the 15 gall with a betta and tetras, what do you think?

Here's what I would do:
5 gallon- a betta, some shrimp.
10 gallon- guppies, otos (maybe buy 1-2 more)
15 gallon- mollies, cories (buy 2-4 more depending on species)
The problem isn't filtering, it's just space. Your cories and otos are schooling, and they need more friends to feel secure. Mollies are the biggest space needers here, so they should stay in your 15gal. You'd need at least 7 tetra, which you don't really have room for right now.. :/
