I am also looking at the flying fox, and my husband thinks they look cool kind of like a shark.
Here is what I have researched.
They get to be about 6 inches
They are very territorial with their own kind, so should be kept seperately.
They do not eat algae very much when full grown, so do not count on him keeping the tank clear of algae.
They prefer densely planted tanks, and lots of hiding spots.
They are bottom to mid-level fish.
There were some at my
LFS, and I am thinking of getting one, but here is the behavior I noticed.
They were kind of testing out the other fish that were in the tank with them. I was concerned that they may be like a
CAE. Or, maybe they were just hungry. The other fish were fine though, no lesions or boo boo's. So maybe they were just saying hi!
Hope that helps, I am still on the fence about getting one, but maybe we can help each other decide!
