I just got some new p's (2), about an inch long. I have a 55g tank, bubbler, penguin 330, and the norm. The water temp reads 79 degrees and the p's are just floating around next to the heater. They seem to like it there the best. I mean, they swim away if I get close to the tank, but for the most part they stay close to the heater. Should I raise the water temp or something. Also, they seem to be playing with their reflections in the side glass of the tank. They go up and down with their noses almost touching the side. Is this a bad sign? I just got them today and am wondering when the first time I sould feed them. I got frozen bloodworms from the store. Also, there is not any bacteria on the bio-wheel yet, however, I bought bacteria start up kit and am using that. Is there any danger to my fish at this moment? How big should they be before I can feed them live fish? Any help would be greatly appreciated. Thank you.
