Amazing job George, looks stunning - how do you do it, endless beautiful tanks and this one with such low maintenance!! Very jealous fish keeperHi Alexander - excellent questions, thank you.
I top up with tap water, but it hardly needs any because it has a tight lid.
The filter is cleaned once a month or so.
Fish load is quite high for a small aquarium. 6 cherry barbs, 4 rocket killifish, 6 pentazona barbs, 2 chocolate gouramis, 6 spice rasbora and 1 bristlenose plec.
Sorry - no idea on any water parameters. I've never tested this tank (or any of mine for years!) I guess a low pH because of the soil substrate.
It is a surprise to me how healthy this aquarium seems with such little attention. The fish are very active and have good appetites. I feed three times a day a mix from dry and frozen foods.
I guess I got lucky and reached a balance where the plants are dealing with the organic waste enough and the lighting is low enough not to cause algae.
Many thanks Blowfish
