gobby and tigger shrimp pair

[petemichelle]

my lfs has a gobby and pistol shrimp pair. I don't remember which gobby but i am pretty sure it was a tiger shrimp. anyway, my question is that will the gobby or shrimp kill and eat my other inverts, worms, or pods? how about corals, especially zoanthids. will they munch on or destroy them? I was at the lfs and was watching them. I saw the shrimp drag what looked like a hermit crab into the hole. I told the owner of the store who was standing next to me and he went in and lifted the rock up and found a lot of shells in there. he seems to think it was probably an empty shell and the shrimp uses them to shore up his cave. I was pretty sure there was a hermit crab in it. anyway my concern is them decimating my clean up crew of snails and crabs, or eating all my worms, I have a lot of spaghetti worms and bristle worms, pods, and other creatures that i have painstakingluy introduced and cultivated into my 150 gal system. one time I bought a 6 line wrasse at the suggestion of the lfs and all of a sudden I didn't have any more worms or pods, it took me a while to notice and figure out. anyway, that was a costly mistake, wouldn't want to happen again. and then I had the tangs with bad behavior who tore up my tank eating all the zoanthids.

can anybody give me insight on the eating and hunting habits of the shrimp and gobby pair? again I don't know which gobby but the lfs said it was not a sand sifting one.

I had a tiger pistol shrimp for a few months and he didnt bother anyone but I had him in a Deep Sand Bed . However they are carnivores and can eat other shrimps, that's why they have the pistol is to kill prey.

I also have a deep sand bed. Very fine sand. Did you have any other shrimp? I have a blood red and a skunk shrimp already. What finally happened to your pistol shrimp, because you said you o let had him for a few months. The time thay you did have him, did you not notice a decline in your fauna?

My pistol dosent seem to do much than work dozing out his cave under my acan rock. My goby sifts some sand but,usually just the top quarter inch.

What kind of gobby do you have? Have you noticed a drop in your fauna (worms and pods and such) population? How about your hermit crab and snail population? Do you have any other shrimps in the tank? How long have you had the pair?
