Cobalt Aquatics Algae Grazer Wafers, 16 oz - Nutrient-Rich Sinking Food for Plecos, Shrimp & Bottom Feeders - Supports Health, Digestion & Clear Water

My plecos, snails and other fish all love these wafers. My only complaint is that they came in a mylar bag instead of the tub as pictured.

My bottom feeder fish love this food! I love that it is made with high quality ingredients. The only negative I find is that not all the wafers sink right away. It is about a 50/50. But I've used other brands of algae wafers, and they all seem to have this issue. Not a big deal, they will sink eventually. And I've found that if you break them in half they will sink faster. But it is rather hard to break them in half. I'm considering buying a pill splitter for it.

They hold together well but my plecos prefer other brands of algae wafers.

Fishes seem to like it fine however. Will be moving contents to different container.

These just arrived today. We purchased these for our plecos, and discovered that our mollies, tetras, and Angel fish also like them. They do take some time to absorb enough water to drop to the bottom of the tank, but, sink they will. The one that I added earlier is currently resting on a plant at the back of our tank, and still being nibbled on. I'll drop another in the tank tonight before shutting off the light, as plecos are more active in the dark.

Pros:-Good quality of ingredients-Lots of veg as main ingredients vs. other brands-Large, substantial wafers-Soften easily on the outsideCons:-They are very, very, VERY difficult to sink as a whole wafer.. they float, even when soft around the outside.-I could only sink them if I broke them apart, even then I have to presoak them.Pros outweigh the cons overall. I tend to presoak food anyways, but I have to use another algae water if I need to quickly feed my fish.

These wafers are a pretty good price and I love the size of the wafer. They are thicker and bigger than a standard nickel. However, these particular wafers float instead of sink to the bottom of the tank. I bought them for my large Pleco so I was disappointed that he couldn't eat them off the bottom. If you're buying them for something that is not a bottom feeder, they're good. But if you're feeding bottom dwellers, skip this product.

I used to use hikari wafers but since the radiation problems in Japan I wont feed contaminated food to my fish, snails, and invertebrates. My fish, snails, and invertebrates actually prefer cobalt to hikari. My test was since I normally use 20 hikari pellets I put 10 hikari and 10 cobalt on opposite sides of the tank. hikari was placed in the normal feeding zone. Everything was clustered on the cobalt side in less tank 5 mins and hikari was left alone till the cobalt was gone and even then they were reluctant to go to the other side. Cobalt tablets are thicker and bigger than hikari wafers so I use 15 now. This food does not cloud the water as my tablets sit for hours before eaten completely.

My sucker fish has not eaten this yet But my goldfish love to play with it it gives them something to do throughout the day

Good quality fish food
