Undulate Trigger is really PITA! Not advisable to add other fishes, except moray eels.
Personally, I find Blue Throat Triggerfish and Clown Triggerfish very attractive.
T. crocea clams are the ones most known for gaping whether it's stressed or not. Give them sufficient lights and make sure no fishes are nipping at the mantles. Keep Cal, Alk, SG and pH in proper range.
If u see bleaching near the inner-center area of the mantle, then it's not having enough lights. Place the clam high up on the LR and position it such that it's facing the light directly, rather than facing the front of the tank.
The worst case is when the clam is retracting badly, pretty much can't save it already.

I'm not in favour of any thing related to gambling.
I know of a close relative who played mahjong with his wife and other friends almost everyday at home. They didn't tk care of his only son and just let him go out and play with some kids outside. But, this boy mixed with bad company and went to steal, sniff glue etc, eventually put into jail at the age of ard 18yrs old. His father was very sad abt this, tried to commit suicide and some time later suffered a stoke, he couldn't work now....
At this point, it's too early to say that casinos are beneficial to SG society.
Proper drawing shld be:
(to main tank)
||

(T-joint)======(ball valve)=====(back to sump)
||
||

(return pump)
U must allow the pump to operate at 5000L/hr, any lesser may cause some problem to it.
I like the rockscaping of Slcw tank, it's spacious and has a natural reef look. But will maybe do away with the extra rock lying at the centre. I hope it's alright for using his pict here.
