New Life Spectrum Medium 2 mm — Sinking Pellets for Tropical Fish 150 g to 600 g - NLS

The New Life Spectrum Medium is a 2 to 2.5 mm sinking pellet made for medium-sized tropical fish in freshwater and saltwater tanks.

The question we get most often is pellet size. The New Life Spectrum Medium is aimed at medium-sized fish: the pellet should fit in the mouth in one go, with no chewing. And like every New Life Spectrum pellet except the Betta line, the Medium has negative buoyancy — it sinks, which gives shy species and bottom feeders time to get their share.

What New Life Spectrum publishes about the Medium

According to the page published by New Life Spectrum, the Medium belongs to the brand's core line, the one the manufacturer presents as its newest generation, built around the Spectrum Nutrition Formula. The New Life Spectrum Medium ingredient list opens with krill, squid, whole wheat flour and fish, followed by a range of marine algae, fish oil, spirulina, garlic and ginger.

The ReefSolution tip

My little trick with NLS pellets

To pick the right pellet size, I simply look at the fish's mouth. The pellet should be small enough that it can swallow it easily, without chewing on it or constantly spitting it back out. If a fish takes the pellet and spits it out several times, before assuming it doesn't like the food, simply try a smaller pellet size.

For meals, I also like to alternate between pellets and flakes. Pellets can be the main food, then you give flakes at some meals. It varies the way the fish feed a little, and the food stays available at different spots in the water column.

And yes, my little trick with Vita-Chem also works with sinking pellets. I simply put the portion of pellets in a small container, add a few drops of Vita-Chem, mix, and let it sit for about 1 to 3 minutes before feeding. If I want to prepare several meals in advance, I can also make small portions, put them in a container or a small bag, and freeze them. That way, my portions are ready and I only take out what I need for the meal. No need to let them soak for 20 minutes. The goal is simply to moisten them and let the Vita-Chem penetrate the pellet a little.

And above all, I only prepare small portions. Once a portion is thawed, it goes to the fish — I never refreeze it.

It's a simple little trick, but with marine fish, it's often exactly these little details that make the difference.

Frequently asked questions

Do New Life Spectrum pellets sink?

Yes. Every New Life Spectrum pellet has negative buoyancy, except the Betta line, which is semi-floating. The Medium sinks as soon as it touches the water.

My fish spits out the pellets — does it dislike the food?

Usually it is the size, not the taste. Before switching foods, try a smaller pellet size, as the tip above explains.

Is New Life Spectrum Medium suitable for both freshwater and saltwater?

Yes. New Life Spectrum presents its core line as suitable for freshwater and marine aquarium companions alike.
