Here's a shot of "Seabiscuit" and her new hitching post... a red tree sponge.
These sponges are beautiful, but you need to know a lil' about them. They can NOT be exposed to air AT ALL. If air gets trapped in their pores, they will start to die from the inside out. They are best kept with decent current so sediments don't accumulate on them. They also appreciate subdued lighting and aren't fond of being under MH. If you have them in a reef, place them in the sand and preferably with some shading. They also need feedings. If you have a nutrient rich tank, no worries. If not, you may want to target with DTs or Phytofeast...something organic.
Enjoy the eye candy. It's not a great shot. Bowfronts are hard to use for photography. I'll take better pics of the sponge tonight.
