I am new to this forum...but NOT new to aquarium keeping...I have had cichlids for the last 17 years...and love them...true personality fish! I have taught adult Oscars to hit ping pong balls to me across the room, and also jump through a hula type hoop...I currently now have a 7 inch marble longfin angelfish ( raised from a 1/2 of inch), a large turquoise severum, & a pleco in a planted aquarium.
