Cool thank you guys - after doing some searching yes it looks more like a monti spongodes. It's still fairly new in my tank only about 2 and a half weeks in but I am starting to see a very slight hint of green showing up when my moonlights turn on... with full lighting under T5's it still looks brownish red and kinda dull... I'm hoping it'll start coloring up nicely.
Do these need to have the base glued down? If you see in the pic I just jammed it between my rocks and it's pretty secure, but if they need to have the base touching a rock or glued then I will do just that. Not sure if it effects it's growth or health when it's just "leaning" on some rock
