my naked clowns hosted this huge orange monti cap for like ever in my tank... now i have a bunch of LPS and they just chill on some duncans... weirdos... my friend has a percula that host his mag float... LOL...
and yes, it looks a bit bleached, but full at the same time... you can tell you feed it... when they're bubbled up like that, it means it has food in it's belly... when the tentacles stretch out and look stringy, it's trying to catch food... the silversides are great, but it will make it grow pretty fast if you feed every other day... RBTA are the largest of E. quadricolor there is... they get twice as big as a normal green BTA...
there's a possibility that by you feeding it, you are letting it stay bleached... it's getting it's food from you instead of it's algae... it's okay for it, but it's still not considered a healthy anemone... if the water fluctuates or anything, it will eat up it's tentacles, move around a lot, or melt... mainly because it's not helping itself to eat... so it doesn't survive on it's own... get what i'm saying...?
RBTA aren't supposed to be see thru... or neon pink... that's not their species... they didn't look like that in the ocean, they shouldn't look like that in our tanks... they should be a solid color... you don't see many corals other than cryptic corals with clear flesh on it's body...
also... all E. quadricolor, like most anemones; are high light... you can't keep them if you have low par PC or VHO lights... they will just bleach up and starve...
