Hello all, I recently inherited what seems to be a pretty well established tank, but starting from a point of little knowledge (other than the stickys here) I'm looking for advice! This will be a fairly long post so apologies in advance, and for my terrible photography. Also, I have no idea what to actually call things, so excuse my wording. I suppose I'm looking for insight in four domains: 1) Equipment 2) Identification 3) Stocking 4) Maintenance 1) Equipment - or, is this the right stuff? It's a 36 gallon tank, with an Aquaclear 70 filter, some sort of sponge filter, and a Beamworks light that has blue (UV?) and UV + white light settings. Also some sort of fish food and water conditioner.

Seems like there's 2 or 3 types, all about 1" 20180623_172113254_iOS by captdavid posted Jun 23, 2018 at 2:01 PM Not pictured: 3 neon tetras (~1", only fish I knew) 2 "sucker" fish, the brownish spiny ones with big mouths that hang out near the bottom or suck on the sides. They seem to always be hiding since I got the tank. One is actually fairly large (5-6"), and the only is ~2". A whole load of snails (easily 50+) Some of the fish seem to have reproduced, and there are tiny babies that hang out near the top. Miscellaneous plants/balls of moss. (wouldn't mind an ID on these too) 3) Stocking - or, the Goldilocks equation. Does it seem like this tank is appropriately, or even overstocked? I would love another medium sized fish, but it seems like there's a lot going on in here already. 4) Maintenance I was told to feed them once a day, change out some of the water once a week, and squeeze out the filters every few weeks. Does that sound about right, and what else should I be doing? Everyone was somewhat traumatized from the move, but seems to have acclimated well enough (though it's only been 3 days). I thought one of the small fish had died, but it seems to have rebounded. Everyone is quite active. Thanks for any and all input!
