Makes me curious. How many Pandas do you have? I had 4. YES, they are aggressive eaters but I never saw an issue as to other fish especially with freeze dried Tubifex Worms and my cichlids... Rope fish doesn't really count as his main food is meal worms. Anyway, I'd press a chunk of dried worms on the glass and the Pandas, of course, would swarm to the chunk and tear it up. The cichlids would just sit back and pick off pieces that the Pandas broke loose. Actually it worked out well. Actually, after the Pandas died, it seemed like the cichlids didn't know what to do with a chunk of worms on the glass. It took a day or two before the cichlids actually realized that they could eat the worms off the glass. Of course I'm sure it depends a lot as to the food type and the other fish.
I DO like how Pandas keep algae under control! What amazes me a bit is that they will strip algae off a plant leaf without hurting the plant. I don't clean the least visible side of my tank just to allow algae and bio film to form for the beasties. I also like how 'human friendly' they are. I couldn't put my hand in the tank without at least one clamping on my hand (see image below).
Of course it boils down to the preference of each person. I just happen to like their antics. I think they are entertaining and comical.
This was the first time I ever had Pandas. Rope fish have always been my favorite but, since I've experienced Pandas, I'm not totally sure about that anymore. When they are available through my local source, Dan's Fish, again I'm sure that I'll get more.
