While unseen behind the lazy-boy chair I was able to confirm a couple things about the tang.
Like a intelligent and opportunistic predator the tang lies in wait for the unsuspecting victim, anticipating the every move of not just the corals in the tank but also the aquariums overseer. Insert Jaws theme music for Tang now.
Once he was sure there was no humans around especially yours truly, he came out for a look then...
Chomp, chomp! I would have gotten some better pictures but this was about the moment when I was going to leap over the chair and some how scold him through the tank.
So it seems this fish definitely eats clam mantle and he even enjoys some LPS from time to time.
not sure if anyone has tried to catch tangs out of a large tank like a 210 on a ladder especially one with an excess of live rock in it...It is not easy, and I have caught my fair share of fishes.
These are 8 inch nets for reference of size, the tang is about 5 inches. I basically was in the tank getting frustrated while the tang learned all my patterns and inabilities to get to certain spots of the tank. After trying all that was feasible I put the nets next to the clam as a tang deterrent while I came up with something else.
Like making my own fish trap! I am a big DIY guy so I have a good idea of things I need to replicate a function of another object.
The BRS container, zippties, fishing line, magfloat,30 minutes, and a dremel were all I needed to get a functional trap made.
Some mysis shrimps poured in through a rigid line I put in towards the top of the trap and 5 minutes later he was already eating inside.
Maybe 20-30 minutes after that I caught his sorry fins out of there!
Now the poor guy is in a 55 sump until I can figure out a fish only tank were a tang will fit in.
Thought I would give an update that the corals and clam are now doing fine without the tang in the tank, good thing too as the brain is my pride and is over 11-12 years old and the clam is about 15 now.
I also have to give a big shout out to Lexinverts for coming through with a fish trap for me so speedily. He has always been a real stand up guy willing to give a hand when he can, he also has some mighty fine corals in his killer Red Seas.
