I put moss in mine and regret it , had a little case of black beard algae I'm dealing with from a stupid java fern . I actually made my tank shortly after reading your thread and got me back into it a little . I did a lot of botanicals and leaf litter on the bottom for apistogramma breeding . Anubias grow really good and love crypt lutea a lot. I almost set up the whole thing for the price of 2 wrasses so it's a win lol great looking tank !!
