My big girl went through about $30.00 worth of fish back when I was a beginner aquarist. She is an expensive pet, but she is awesome. Night crawlers that are three times as long as her are just spaghetti and feeder guppies don't last long at all. I have had serious luck with keeping cichlids with them. They can hold their own and are too fast for them. They have been with them for about six months and just keep growing. I imagine I will have to change their tanks up eventually, but for now it's neat to have them together.
Anybody want to put up pics of their ACF? I'll put one up later.
