My Tomato plants are doing great with high stalks and broad leaves. They have outgrown the stakes, now I have to run for higher stakes. I only put 8 plants in, 4 Juliet Grape Tomato and 4 Big Boys. Neither have produced any red ones just yet, but they are loaded. This is the first year I did not pinch off the tomato plant 'suckers', which means alot more stalks and more tomato's.
I usually prepare the garden with some 10/10/10 in the spring, and I spread some Epsom Salts about a month after the plants are in. Then Lime in the fall. That combination seems to work well for tomato's so far. Epsom Salts (Magnesium Sulfate) turns your tomato plants a healthy green color. One teaspoon per plant spread around a foot of the tomato stem works wonders. You can add Epsom Salts anytime of the year to perk your tomato's up.
I don't think those Hornworms would work for Catfish, but you never know until you try. Birds don't even bother with them. The juice that would come out of those hornworms would probably be highly acidic. That Wasp might be the only predator that seeks those Hornworms out as a food source for their young.
Anything that can eat and digest leaves from a tomato plant can't taste too good.
