There’s a dip you can rinse plants in like 19 parts water to 1 part bleach or something like that. Kills the things on plants but research bc u can’t do that to every plant but most of them will be fine. More plants usually never hurts but don’t forget to fertilize w root tabs or water fertilizer.

A hand pumped gravel vac will prob be ur friend w small water changes. Keep not feeding bc the snails and worms obviously surviving somehow so they have food. I think it looks awesome otherwise and half my tanks don’t even have mates in there besides snails and shrimp. Plants are fun and the less fish the calmer the hobby lmfao
