I really need to stay away from the fish stores for a while. I seem to ignore my own advise when it come to fish. : I wanted a little diamond goby for my sandbed and one of my local stores had one so I told them to hold it for me. When I got there I realized it was one of a mated pair that were cruising around together. I couldn't bring myself to separate them, so I bought both! Now this would be fine it I had a large tank, but I don't. So I will be feeding a lot of mysis to these guys. They are cool and already burrowed a home under a rock, but I can't help feeling really guilty.. I guess the answer it to buy a big tank so I can keep everything. hehe .. hmmm. Anyway. Impulse buys. Are you guilty?
