Does This Seem Like A Good Combo???

[WarWolves]

i have a 55 gal wide tank with a 7" Wolf Fish (Hoplias malabaricus) as well as a 9-10" Water Cow (Eleotris picta) does this seem like a good combo??
I was thinking maybe since the water cow is bigger than the wolf then the wolf wouldnt try to kill it and if i keep them both well fed then the water cow wouldnt atempt eatting the wolf does this seem like it would work??
please any tips would do

The wolf should easily outgrow your tank. You haven't given much info as to your plans, so don't want to be presumptious though I can't see it working. Though I'm no wolf expert or goby expert for that matter either. If wolves get as aggressive as the impression I get from doing a little research, I can't see it being viable. Best bet is to buy too bigger tanks and research a little.
