Why

Zucchini (courgette) is one of the most popular and recommended vegetables for aquarium fish, especially herbivores and omnivores. Plecos, goldfish, cichlids, and many tropical fish enjoy it. Blanch briefly to soften slightly, then attach with a vegetable clip or weight down with a fork. Most fish will nibble at it throughout the day. Remove within 24 hours before it breaks down and fouls the water.
