yea, bumble bees are really nice. I have 3 of them in my 75 and despite the fact that some say that they will starve if forced to compete for food, mine are doing great. They don't hide and I see them eat blood worms, or brine shrimp, and even Omega One Marine Pellets from time to time. They share the bottom of my tank with Dragon (violet) goby, a columbian shark, a hogchoker, and some fiddler crabs. They don't get messed with at all, and I have a GSP, a F8P, scat, a mono, a needlefish, a green chromide, and some mollies. I was really worried that the Needlefish would see the bumble bees as food, but they are fine. I honestly thought they were going to the first fish to get eaten in the tank. Boy was I wrong! My Figure 8 killed an albino channel cat, a blue channel cat, and a needle fish. He's a tough little guy, but the GSP is twice his size so I hope they get along. BTW, Bumble Bees are cool to watch.
