When you think of the phrase 'feed the fish', your first thought may be of tossing food pellets into a backyard pond. However, synonyms for this action can be used to describe feeding all sorts of sea creatures. If you're at an aquarium or on a fishing trip, you might use the terms 'bait the hook', 'lure the fish', or 'chum the waters'. Alternatively, if you're sustaining aquarium pets like goldfish or bettas, you might 'give them their daily ration', 'serve up their meal', or simply 'feed them'. No matter the situation, giving aquatic animals the nutrients they need is crucial for their health and survival.
