I haven't updated this thread in forever. I lost the pair of seahorses months ago due to an unknown cause. Now the tank is just a fuge with tons of my purple sponge growing in it. The mother colony is ~18" in diameter.
For now I have just been getting different nudibranchs to see if I can get any to eat my sponge or other sponges I find.
Heres a few pics:
