ok calm down I have had gold fish before and these are about a half inch long, these are feeder no biggy. I have had them for 2 weeks and done 2 water changes and they are doing well. The water is a nice 70 and they are pretty happy. I actually dumped the sandy grael that came with the bowl it was a PITA to clean so they jsut have the marbles.
Anyways they are happy campers.
