fish compatibility

[saska]

I have been having some problems with fish compatibility and plan to prevent any further fish lose from my clown fish's aggressive behaviour. I am fairly new to keeping salt water aquariums, and have tried to keep my fish within the limits of the tank capacity. Originally I just had a 14 g tank with two clowns, a dragonet, firefish goby, golden wrasse and a blue damsel. After my clown fish killed my wrasse, I set up a 29g tank to separate the fish as I was sure my clown was too large for the tank, and that was the cause for the aggression. I was able to put my clown fish and damsel into the new tank last week, and tonight when I moved my goby into the new tank it was attacked by the clown which ate its tail! I immediately moved the goby back into the smaller tank, but I don't know why the clown would attack the goby, they are similar lengths - so I'm not sure if that was the problem. Or territorial, because the clowns were in the new tank first. After this, I also would like advise in future additions to the tanks and to check compatibility. I have been doing other research also. This is want I would like to have, or have already,
14 g tank:
firefish goby,
2 small bangaii cardinals
psychedelic mandarin
wrasse
29g tank:
2 clown fish
blue damsel
watchman goby
peppermint shrimp
cleaner shrimp
bristle star
green mandarin (not untill this tank is more established)
Would these combinations work?

Those combinations will work, however the adult sizes of the watchman goby and brittle star can become quite big. I would either get rid of the two clownfish and get the goby with a pistol shrimp OR keep the two clowns and get rid of the goby.
You are going to have a heck of a hard time keeping a mandarin goby in a small tank without a refugium. It's nearly impossible. I wouldn't get the mandarin at all for either tank.

I'm going to start a refugium. So far I have been adding copepods and tiggerpods to the tank directly, but that does get expensive, so I've got some that I will try to breed and keep the supply strong. I started doing this when I first saw the mandarin losing weight. It seems to be working so far. But I won't be gtting a second mandarin for quite some time, my 29g tank is too new and I don't have enough tiggerpods for two mandarins at this time.
Thanks for your suggestions, I will wait to get the goby and mandarin until I'll be able to get a larger tank in a couple of years. I don't want to be getting rid of the clowns, since they are already here and it wouldn't be fair to trade them.
