I did some research myself and was very interested in the gulper catfish, hairy puffer, and red wolf fish. However, people seem to say all three are very inactive during the day or non-feeding times which is preventing me from making a purchase. I also did some research on the flowerhorn, but I'm not a huge fan of empty tanks with only water and a fish and I also feel like there is a lot of luck involved when it comes to picking a flowerhorn with good genes( big kok, good coloring, good lifespan/ health). Should I go for one of these 4 fish or are there any mid size predators out there that are also active in the tank?
