I'm probably still a beginner, though maybe verging on intermediate. I started about a year ago with my first tank. I'm moving in a couple months and trying to plan ahead. Can I ask for advice on what to keep when downsizing into just a 5gal?
Always wanted a small small tank, but started with a 29gal because that was what I saw recommended for a beginner. Already downsized to a 12gal without having to get rid of anything, but now I want to keep just the 5gal. I'll keep it high tech and pretty heavily planted.
The 12gal is doing really well even though it's overstocked. Ammonia 0, nitrites 0, nitrates 0-5 range even with adding liquid fertilizer every other day (I could never keep them that low in my 30gal even; I think the light is better suited to the smaller tank). Currently have: 10 ember tetras, ~10 japan blue hybrids, 4 nerite snails, ~5 blue velvet shrimp, 1 betta fish (really peaceful guy, doing great in community setting), some pest snails, and 1 pea puffer (on her own in a 5gal). I'd like to keep the shrimp and at least 1-2 nerite snails. Planning to rehome the pea puffer and not transfer any of the pest snails to the 5 gal. The japan blues are beautiful but super super active and I don't think they'd be happy in a 5gal, not to mention the population getting out of hand quickly.
Thoughts on what I can realistically keep in the 5gal? In addition to the shrimp and nerite snails, can I also keep some of the ember tetras? Or the betta?
P.S. Please be kind -- I've always been mad when I heard about people getting a dog or cat and getting rid of it a couple years later because it isn't convenient anymore. I guess fish feel different than a mammal, but I might be equally guilty. It's ended up being a more stressful hobby than I anticipated and I'm short on time and space.
