For certain, Orange Tree Sponge is my pride & joy. I received two of them 4 months ago. They have done well in each of my displays, 120G & 75G. Due to maintenance upgrade on 120G, a few days ago, I put both Orange Tree sponges in 25 year mature 75G display.
Yes, I saw Hippo tang and Sailfin Blennie grazing on tree sponge occasionally. As time past, I noted Algae Blennie grazing more aggressively as later determined by missing biomass in side of sponge. Now new growth as signified by emerging translucent growth in every spot eaten by Lawnmower & Hippo.
