Sweet! :) I plan on converting it to a NPT when I get the money together to get it set up, but for now I have a filter that is for a 20-40 gallon in there. There are also SO many silk plants and hide-y caves its ridiculous
.....I wouldn't suggest putting a school of neons in a 10 gallon with a Sorority. While neons are generally peaceful and you sound like you have great filtration, it comes down to space. Neons are an active schooling species that need space to swim around and school......with five active betta girlies claiming all that swimming space, there really just isn't enough for a proper school of neons to be comfortable IMO.
That would be too heavy a bio-load. 5 females is almost fully stocked, so adding a school of neons too would be too much. It would also be very cramped, so fighting would be likely.

Many of my scaly friends from my original tank from 2011 have passed, except for two! I am in the process of re-doing my tank. :)
