Hey all, I have a 125 gallon tank(6x1.5x2), currently with only 6 smaller fish(approx 2-3 inches), bala sharks, pangasius catfish, and silver tip sharks. I'm trying to figure out the most efficient way to feed them as they don't seem to often see/find food as I place it in the tank. For the moment I only have flake foods(shrimp and plant mix) which the sharks seem to hate even if they do see it and shrimp pellets which the catfish seem ok with, but the bala's don't seem to like it much. Regardless the fish seemingly find like 10% of the food I toss in and I don't want to just throw food in that'll be uneaten and make a mess. I'm considering getting some blood worms and beef heart and maybe tying it to a suction cup in the mid of the tank, but I'm unsure of any way beyond that to give them easily accessible food. Any ideas?
