I have a brown darter that has taken to flake food, but will eat live food
if available. Most other darters that I have had needed live food. In
addition to what you are feeding them, they will of course eat other fish. I
have been amazed at how big a fish they can consume in ratio to their own size.

yes. Especially smaller bottom fish. I have had a larger crayfish sit on
top of a submersed air filter and take a whack at anything that came near,
no matter what the size. That individual made it back to the creek.

The experience that I have had is similar. I do have a shadow bass that
co-exists with a brown eel, but the eel is the dominate fish in that tank.
I have had luck with some aggresive salt water fish I have caught. What I
have done is when I introduced the fish to the tank (juvenile coca damsel),
I separated him in the tank from the other fish with a clear plastic
divider. I arranged a rock formation in his area that he could feel
comfortable in. After about a week I removed the divider. He now tends to
only protect 'his' area of the tank. In the past when I have introduced
aggressive fish into the tank they attempted to take over the entire tank.
This approch may work for sunfish also.

I have never caught madtoms. I would like to hear about other peoples
techniques for catching these fish. I have caught a small sailcat, once. It
was in a homemade trap in which I used nylon screen instead of metal screen,
like the manufactured traps use. I have theorized that maybe madtoms/catfish
cannot enter the trap openings unless they are more flexible because of
their pectoral spines. What do you think?
