Monty, blue streaks around the face and gill area sounds like, to me, green sunfish. They don't provide enough to feed your catfish. Toss them out when you catch them. Also use the search function here to find out about crappie in small ponds. For forage you need bluegills. Check with local feed stores to find out when the fish truck is coming. It should be advertised. Call them to see what they are bringing. Don't let them talk you into Hybrid Bream. You can also contact Bobs Fishing Hole by Eagle Mountain Lake. Bob is at 817-237-7292. He carries bluegill and shellcrackers. Just make sure you do this stuff soon before the water gets too hot to accept new fish.
