I always mix my fish with worms. Ive always done that. I have never given just fish during a meal. I just know that the fish is plain with nothing added and it is cut into filet sized pieces. 2 in each.
So from those kind of fish that I mentioned what ones are ok for them to eat.
ANd Steve I very much respect anything that you have to say and when I am able to buy fresh I will. Just right now I have to go with this.
