Diamond Goby vs Mandarin

[hallzy]

I have a diamond sleeper goby and a Mandarin (both of which i got at the same time) and the daimond is nipping at the mandarins tail fin. This isn't really normal behavior for a diamond goby is it? I know you cant mix them with other sleepers or jawfish but i thought they were peaceful with most other fish.
He doesnt really even aggressivly nip though, like hes not trying to hurt him. And it doesn't seem to bother the mandarin, but his tail fins are getting a little tore up. What should i do?

Bump...I have a diamond and want a mandarin soon

if its not too bad i would do nothing. you could separate them. bottom dwelling fish can get territorial.

when did u get these two fish? the goby is probably territorial when the mandarin gets near. ur profile says u hv a 29 gallon? not sure if thats good enough for a mandarin unless it eats prepared food.

yeah I doubt you can maintain enough pods to support a mandarin
if the diamond doesn't kill him (which i doubt he will)
he'll most likely starve

How long have they been in the tank together?
