I've got a naturalistic setup which requires a water change and some algae scraping like once every 2 months, I only feed a small amount twice a week as well as remove duckweed once a week.
My goal was to create a miniature self sustaining ecosystem and I've achieved it pretty well.
Started with 2 honey gourami, couple of guppies and 6 cherry shrimps, as well as snails i had as hitchhikers so I added 2 assassin's.
It's been a little over 8 months and I've now got a shrimp population that's more than triple the original, healthy guppy population kept in check by the HGs who eat any guppy fry too stupid to swim away fast, snail pop is solid and to a point where they are a good CuC but not running the tank.
Tried breeding the HG's for a little bit, had success but I can't facilitate seperate grow tanks so left the fry to be eaten and turned up the flow to discourage more breeding.
Key point in this entire tank has been a LOT of vegetation and an oversized canister filter. If you're going to start a tank, I'd 110% recommend an oversized external canisterfilter if at all possible, it works wonders in keeping your water stable.
