ok so i finally got my tank good and established for about a month after cycling was finished. my question is at my LFS there is a really cool cow fish i asked the store keeper about it and she was really nice.she admitted she wasnt the best person in the world for salt water and that she was the only one they but siad she was pretty sure the were ok with other fish but wasnt to hardy. and if it got scared it would release poision in the water that could kill the fish and its self.so she said since she wasnt for sure and didnt want to sell me something that was going to be a lot of trouble and i admittidly dont know a whole lot about keeping a picky eater in my tank she would hold it for me until tomorrow so i could look on the computer and just call her tomorrow and tell her if i want it or not. so any information you could tell me about would be greatly appreciated. thanks in advanced
