Thank you everyone, I suspected the small one was a Jewel but I'm far from being any authority. I was at a complete loss about the bigger guy. I guess the next question is, are they going to be alright in with the new guys we put into the tank 2 yellow labs and 2 cobalts? And will they be alright as singles instead of as pairs. We had another of each but had a filter catastrophe about 2 weeks ago and lost their companions.
