My new tank is about 33 Gal/ 125 Litres and it's been set up about six weeks. It has a good filtration system and I have loads of live plants with sand substrate, some driftwood, as well as a few marimo moss balls! Current stocking is 6 zebra danios, 2 lyretail mollies and 5 platies (don't worry about the babies, I have a separate quarantine tank to hold any survivors which I can then sell) I also have a load of cherry shrimp in a smaller tank, which I will be moving over some time. All the fish get along really well so far, they love all the plants and the sand substrate. I am hoping to add a group of corydoras (main reason why I set up with sand). What do you all think? And if this was your tank, what would you stock it with?
