new to this question about a tongue coral

i had a tongue coral in a 10 gl tank with live rock,then moved it to a 30 it started dieing and now it no longer shows any signs of life i think its dead. what went wrong?

 

Welcome to 3reef!
Good Question, Could you tell us a little more about your tank?
Did you use the same sand?
Did you use the same water,live rock,lighting?

 

no the sand was left in the 10 gl but same light i'm thinking it's the black sand but not sure. the 10gl had white sand. it did ok in the 30 for about a month now its all white i put it back in the 10gl but i think its dead.before i try again with another one i need to learn what to do.

 

It is more likely that it died due to the overall change than from a specific difference. Sometimes the shock of being moved is all it takes to put a coral into decline. Add to that the numerous minor differences in current, light, water, etc. ... it's tough to be put in a new tank.

Also, that type of coral can very easily suffer a minor tear in it's tissue which is enough to start a decline. (That's the major reason they always need to be placed on the sand ... resting on rock can cause abrasions when they expand and contract.) You have to be extremely careful handling them.

 

thank you all, now i have some understanding about where i whent wrong i'll get another one and try agian. maybe i'll have better luck.
