The photos I've posted are a 1-week before and after comparison taken in natural indirect sunlight. I'd like to note that the fish in the photos was a new arrival; some end up losing a bit of color from shipping stress, though NLS boosts it back stronger than other pelleted foods.

I think this is a great diet when used in conjunction with other foods. I offer NLS along frozen bloodworms and brine shrimp in addition to a small amount of steamed vegetables.

The small pellet size is better for fish and the ingredients are wholesome.

I can't speak for how well the product works by itself, but I've had fantastic results in combination with other foods.

I've used Thera A for about 8 years now. My fish always love it. I dispense it with an auto feeder that I purchased on Amazon (http://www.amazon.com/gp/product/B000F7OOJG/ref=cm_cr_ryp_prd_ttl_sol_20). This makes things very easy. My only complaint is that even though it boasts that it is a "sinking" pellet, they do not sink very well.... But I've never found a pellet that actually sinks well. The problem is that you are dealing with a DRY pellet dropping onto a water area with surface tension. Thus the surface tension must be broken. I've found that they best application is placing my feeder over the return flow of my water return. This allows the turbulent water to push the pellets under. Unfortunately most tanks probably wouldn't have this, thus you still likely will have to stir the pellets into the water to get them to sink.

I keep a variety of fish and can comfortably recommend most NLS foods. They have high quality ingredients with less fillers than competitor's foods. For Fancy Goldfish as well as Dojo Loaches and other typical tropical community tanks I use a combination of the Algae Max and Thera A pellets. For Betta tanks I use the Betta pellets. Fish get noticeably healthier and more vibrant in appearance when fed good diets and these foods fit the bill at a decent price.

I buy the largest sizes and use small containers to feed directly from while I keep the rest frozen to stay fresh and hold nutrition in.

This fish food is great for both of my tanks. It has garlic in it and does not cloud the water. My fish eat it vigorously. I respect the New Life brand for all fish food needs. I have used the 1mm size food in my community tank and fancy goldfish tank for 5 years.

This is currently the best dry fish food for general marine reef aquarium use. The .5mm Small Fish Thera+A pellets apply here as well - big fish may have a problem with these two smallest size pellets, but tangs do quite well with both smallest sizes. Anemones and many corals love it as well. Some fish really go for this food rabidly right from the get-go while some have to get used to pellets, but they do.

I have used Thera+A for about 5 years now, and as my staple food for the last two years since Vibragrow small marine pellets went out of production. Thera+A does wonders for color almost as well as Vibragrow, naturally and helpfully for best fish health as well - not just for good healthy color. Thera+A is better in some ways than Vibragrow was, but not quite as good in other ways. Thera+A is still currently king of dry fish foods - rest assured.

Some dry fish foods really should not be used as a staple food and will not maintain top health like this one does. Thera+A has not only the wide variety but also the proper variety for maximizing fish health. Thera+A also has garlic which does seem to make some difference as well, in my opinion and in the opinions of many other marine reef hobbyists as well. I used to make my own frozen food mix with very similar variety, and sell it locally too, which also had Selcon ingredients in it as well. It was tops for taste (according to many, many fish) and for variety and health too, but was not so convenient to make or even to feed, and not quite as good on the color enhancement for the fish. The pellet form of Thera+A also locks in the vitamins (and other nutrients), until the fish can eat it, better than flake or frozen foods do.

I had a yellow tang with lateral line disease, and started feeding the fish Thera A. The symptoms have all disappeared.

I gave this product 4 stars, rather than 5 because It doesn't sink. When I pour the food on top of the water, most of the food ends up in the sump. Make sure you hold the food under water first. Most of it will sink. (A little still will go back to the top).

All of my fish devours this! I love that it stays afloat for a bit for any fish that likes to eat at the surface, but also sinks down for the bottom dwellers. Definitely keeps all of my fish healthy and their colors vibrant. Highly recommend!

This food has been responsible for keeping very difficult to keep fish such as an Achilles Tang, Powder Blue Tang and a Moorish Idol, not only healthy and colorful, but they are as thick as the ones I see diving on the reefs in Hawaii. This is an excellent fish food
