I have a 2 gallon KK for Beau. It has a rock with an anubias plant tied to it. I had wisteria, but those rotted due to the wrong lighting (I recently got the correct lighting). Beau loved weaving in and out of the plants, so I want to get some more for him. I know the tank its small, so I can't get many. I was thinking I could put plants in the back and leave room at the front so he can have some free space to swim. I want plants that are easy to care for and can handle 100% water changes every week. I was thinking I could get some pennywort. Does anyone have any suggestions? Also, should I be using fertilizer?
