Anyone here have any experience with banggai cardinals reproducing in their tank? I've been doing some researching to try to figure out what's going on with the two I have.\nThey've only been in the tank for 4-5 months, but in that time I've noticed a kind of pattern they go thru. For a few weeks the larger of the two eats like crazy, even making it hard at times to get food to the other fish. Then suddenly the bigger one will disappear behind the rocks for a few days, ignoring food and only poking out of the rocks occasionally. During this time the larger one looks like Marlon Brando's Godfather...its face and cheeks all puffed up. And it does that 'yawning' thing constantly.\nI also have a very peaceful, laid-back spotted cardinal and during this time the smaller of the two banggais takes it upon itself to pester the crap out of the spotted cardinal.\nThis phase lasts only a few days, then the larger banggai comes back out looking normal...and everyone plays well together again.\nIs that what could be going on, or...\n \n...maybe I spend just a little TOO much time watching my fish...?
