Fishkeeping Facts and Tips

Vegetarian fish Some catfish have a largely vegetarian diet; feed them potato, lettuce, cucumber or blanched peas. Some of these will have to be weighted down, or held in place with a commercially available 'lettuce grip'. As with all fish, do not over feed; remove uneaten vegetable matter after a couple days
