I got a red arowana and I was wondering if I fed it frogs or toads from outside would it be ok or would that make my arowana sick? Some people tell me to feed it frogs and toads from outside because there are alot around my yard and they said it would be good for it. Also my arowanas back fins are rotting a little or someone told me it might be burning away b/c of pH level or something. What can I do to help fins restore? What is good pH level for red arowana? Any help or suggestions are very much appreciated. Thank you.
