Inverts in Aggressive tank

[barkdog]

I've got a klunzingers wrasse, porcupine puffer, v. lion, and a humu trigger in my 180. I was wondering how big an invert would have to be to make it with this crowd. The reason I ask is I have one of those hermit crabs in my invert tank that is growing super fast. The shell he is in now is about the size of a racketball. Only a matter of time until he is actually bigger than the humu and puffer.
Could I ever transplant him into the aggressive tank? It would actually be nice, so there would be something on the ground to stir up the sand a bit and pick up scraps from these messy eaters.

i think so with a hermit crab that big
but you never no with the agressive fish

What about things like a horseshoe crab or a conch that spend time in the sand bed. They would help the ecosystem quite a bit. Or would the wrasse, trigger and puffer just peck them apart?

Horse shoe crabs are a poor choice for any aquarium.
However, a fighting or queen conch would do well as long as they are not too small.
I have several of each and they do a great job of keeping the sand bed gently stirred.

I've wondered abotu large hermit crabs also, but they can also attack fish, no??
Conchs are great, but some fish blow on sand searching for food. They could very well find conchs in there!

i have huge conhcns in my tank, queen conchs, crown conchs and fighting conchs. they sey they will fight but with a huge tank they never run into each other soo i took my chances and all is well. However i had a HUGE red strawberry hermit crab in my tank that was about the size of a baseball and he was fine for along time until one day he just started attacking EVERYONE , evan the fish would swim by and he would try to grab them so unfortunatly i had to get rid of him!!

i have several big hermits in my 210, they dont bother my fish.
Now my new 9'' golden puffer might find them very interesting?

I added 2 hermit crabs and 2 snails to my aggressive tank and they have really made a difference in my tank. At one time I had an algae breakout but the snails have quickly taken care of that problem and now I can keep the light on a few more hours a day. The hermit crabs were added to take care of the uneaten food and to keep the sand bed stirred. What I didn't expect was all the crap(dookie) that they would leave in the sand. The crap is also being stirred in the sand but now I'm concerned about the buildup and eventual crash of the tank. While I do like the addition of the hermit crabs to my tank, I am seriously considering taking them out.

could i put two of theses in a 125 with lion, porc, panda face puffer, bursa trigger and a small moray or would they get eaten?

I have some smaller hermits in there now but they hide in the rock and some come out but I have lost at least 70 hermits and snails in 2 years due to them being eaten but I think these big guys would get messed with but if they are big then
