My experience with Senegals is that they ignore anything they can't fit into their mouth (And sometimes what fits into their mouth doesn't necessarily fit the rest of their body, resulting in choking and death). But I must say, depending on your shark and the goldfish size, your SH is probably going to be in hiding most of the time.hi i would like to ask something because tomorrow i will add my new 6' senegal bichir to my tank. right now my tank had one 5' dwarf snakehead and with 4 goldfish and 1 ID shark . i would like to ask if they would work fine with each other?
I have kept my channa lucius with datnoids, various bichris, wolf fish, clown knife fish, and red hook silver dollars. For a year or two now with no problems what-so-ever. The channa gets along with all the tankmates and is often hanging out with my hoplias. I have had no snakehead related deaths and the snakehead mantains an active life with a healthy appetite. My only complaint is I can't find more lucius to get a group going in my community.
