So I spent a little time throwing in some rock in my 75 gallon. I think it ended up coming out ok. The lava rock really helps fill out the tank. There are two black 3" PVC elbows hidden on opposite sides of the tank to serve as potential nesting places. I might scatter a couple more towards the middle just to provide more options.
Currently I am doing minimal water changes. Topping off every day and using some Flourish Excel to get rid of some of the algae that is appearing here and there. Weekly dosing for plants consists of small doses of KNO3 and KH2PO4 along with Seachem Flourish.
The firemouths are starting to color up and are very active in the tank. I think I *may* have one pair but am still unsure. Two of them kinda hang out together but aren't really side by side or defending an area.
