Here is my 20 long shell dweller tank- Multifasciatus and White Calvus. In the tank I have several Java ferns and some Marimo Moss (algae) balls. My question for all you plant people is what other plants do you think I need in there (lowlight.) I've been dosing Flourish once a week and have and Aqueon modular led fixture X3 bulbs. 10000k and 1 colormax.
