Do Fish Benefit from Liquid Food?

roibenami · Jun 3, 2017

So from my understanding, saltwater fish (unlike freshwater fish) do drink water. The salinity in their body is lower than the surrounding salinity and therefore water always wants to exit their body. To compensate they have to drink their surrounding water all the time to keep water in their bodies.

So my question, does that mean that fish benefit from food they might ingest as part of their drinking? For example, if you would take a product like Red Sea's Energy A+B Which is a complete diet in a liquid form (protein, carbs, fats, amino acids and vitamins). Would the fish benefit from it?

If it would... to what extent? could you feed your fish only liquid food? Could this be used to "force-feed" finicky eaters? lol... just some random thoughts I had.... I'm pretty sure i'm off here but I would like to get some professional confirmation...

Very good question.

The amount taken in will be very, very small. If you add enough liquid organics to the water to feed a fish with the small amount of water they take in, you will drive a large bacterial bloom.

So it's theoretically possible... But not practical as I would need to feed a lot more and it will lower water quality more... Is that right? (Bacterial blooms are not that bad, a specially if you have a uv... So i'm just assuming that it will be a water quality issue)

When you add the energy AB product the whole tank becomes very green and then it just disappears after a few minutes... It looks like the water is full of food and the fish are constantly drinking it until it's gone... That's why I thought...
