Yes definetly agressive fish. I had six in heavily planted 20 high, moved them to a heavily planted 30, removed 3 and put them in a "fin recovery tank". Mine set up a pecking order, big dog out front and the rest behind him/her fighting to see who was next in line. Every now and then big dog would hammer one of them. Now they are all in a heavily planted 10 gal along with 2 am. flags (who ate more than just the algae in my other tank) until I figure out what to do with them. Fins are damaged but not near as bad as before. tc ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
