I recently converted my general 90 tank to all Sps. Took me three weekends to place all the 65 frags I have in rocks. I have had a problem with a long time hitch hiker----a green blue crab about the size of a cell phone..... Well, this morning when I checked the tank, it was as if a Tornado went through. 7 frags have been trashed..... Just boweled over, eaten etc. I dont know what to do....... Have some 16 Ora frags in the tank. He hides during the day in a rock tunnel and I am thinking of just blockading it to trap him inside.He is very caustious and cageyyyyyyyyy... Any recomendations?????
