Unfortunately, the rope fish will almost undoubtedly someday realize that the neon tetras and then zebra danios fit in their mouths, and are tasty snacks. They aren't particularly aggressive fish, but you'd be hard pressed to find any fish that won't eat something bite sized.
I think the upside down catfish also goes by the name Blotched Upside Down Catfish. At first he almost never came out, but now he comes out a few times a day. I think eventually once I started dropping algae wafers, he became more comfortable with his environment. He swims alongside the rainbowshark when he comes out, and when he's in the cave more often than not the algae eater goes inside and stays for a while.
I wanted my community to be a nice mix of fish, and there are some rules with some fish I found to be bendable. The only way to find out was by trial and error, and a few times I found out the hard way that some rules cannot be broken. Fortunately, some I found can and as of right now my community is pretty much established, and everything seems to be getting along ok for the past few months.
I was having trouble keeping the neons from the start, and I knew there was a possibilty the rope fish could see them as food. But like most fish, if it can fit in their mouth, they might think the same way. I'm taking a chance with them, and it might turn out to bite me in the butt but hopefully not. Usually during the day around 1 o clock, both ropes will come to the surface and wait for some tubifex. Then at night, they will poke their heads out of the cave and wait for me to drop a piece of shrimp. I'm hoping this keeps up to avoid them looking at the tetras as food.
Thanks for the help I appreciate it.
