I probably won't add much more for plants. if any I would like to add some kind of moss on some driftwood like taiwan moss maybe. As for fish its pretty well stocked for my filtration once everyone is all grown up. I have 2 prochilodus, 1 royal clown knife, 2 clown loaches, 1 silver aro a 4 lined pictus cat, a freshwater moray eel and a lima shovel nose. I might be adding my wifes 2 bala sharks and a synodontis cat out of her 55 gallon as well once they outgrow that tank.
