I am very picky about choosing my fish so I love them all but I have to say that my very favorites are my angelfish and my otto's.*twirlysmi *twirlysmi
Archerfish all the way. Once you've seen them jump out of the water to grab food, or spit at it to knock it into the water, nothing else will be cooler .
I dunno... my multies are fun to watch behavior wise... always hanging out on the front porch of their shells, going in and out every now and then. My blue ram is the prettiest fish I have, though.
Right now my favorite is my "bouncing baby Burrfish" that I collected from a wicked surf at the beach. The fish looked like a little marble floating about. I scooped it up with my large aquarium net and it has doing very well ever since.
