I know this is way late, may be old news to you by now. But that's over stocked. Rule of Thumb is 1 gallon per inch of fish. Just to make it easy, I would count your fish and 1 inch per. So you have about 1.5x recommended, plus shrimp and snails. If you stay up on your water changes, like never longer than 7 days, and probably better with more often than once a week, you'll be okay. But that gets tiresome down the road. If you go out of town for a week or just have a hard weekend you'll skip a week here or there. Or just may come home from vaca to a few dead fish and a bummed out pet sitter. lol. People take it personally some times when a fish dies on their watch.Ok got it thanks. For the record do you think thats over stocking? 6cpds 3tiger Endlers 3guppies 3 hara jerdoni? And maybe a handful of snails and maybe some shrimp.
