i got them both at petco after MONTHs of looking lol

Oh ok. Yeah, I don't use any filters, but changing every ones water twice a week can be really time consuming with 19 fish.lol

I don't use filters on any of my tanks. But, if you don't use a filter you'll have to do water changes a lot more often. For your 2.5G it should be cleaned twice a week 100% if you don't have a filter. I don't know anything about them or cycling. You could make a thread about it and the people who know everything about filters can answer your questions. Sorry I can't help!

Thank you! I got most of them at Petco.
