I just ordered two pair of Fundulopanchax Gardneri Killi. I did my research but missed their aggression. I have two tanks. One is 10 gallon planted with Red Cherry Shrimp & Fancy guppies the other is 40 gallon planted community with only Red Cherry Shrimp, Ghost Shrimp & harlequin Rasbora in it now. I was going to put a pair in each tank. However, I just read that they will tear up my fancy guppies. So now what do I do? Do I put both pair in the larger tank and change my stocking options? I was going to get a pair of German Blue Ram for the larger tank & a Honey Gourami for each tank. I can't get an angel fish for my big tank anymore I guess. They are being shipped to me so I cannot send them back to the store. However my sister is going to set up her 10 gallon, that's another option. Any suggestions please help me.
