Senegal Bichir getting to big for his britches

[LillyPad]

My Biker is about 6 inchs now and is more active and aggressive than ever! He has killed my dwarf gourami, ate all 13 of my regular neon tetras and is now set his eye on my female marigold swordtail! He also took a chunk out of one of my 4inch tall black angels. I love the guy and want to keep him and give the angels away to my friends grandma who has a 75g but my wife wants me to get rid of my biker texas ranger! What would you do in this situation?

Birchirs are predatorial and will eat anything small enough to fit in there mouth. Ive even had mine bite at bigger fish possibly just "testing" what they were smelling. Birchirs get fairly large and should not be kept with community fish or anything too small or they will most likely eat everything in your tank. If you want to save your fish you will have to take the Birchir out.

Update. Black angels moved to friends grandmas 75gallon.
