I started with rosies at first, but they were dieing like crazy. I switched to goldfish because they are much bigger, hardier, and the same price as the rosies. The goldfish are so messy though. My filter just got disgusting in one week. I just upgraded the feeder tank from a 10 to a 28, so hopefully the goldfish won't seem as messy. What kind of set up do you have for your rosies? Are you successful at keeping them from dieing every day?
I do want to start feeding them other things. They haven't eaten anything else yet. The Mono/Ocell has gone after shrimp but just spits it out. The Kelberi is interested in nothing but feeders. I am gonna switch to the spot feeding one feeder at a time then dropping other kinds of foods technique pretty soon here.
