I’ve used this block for my Plecostomus and it’s been a game changer. The fish eat it consistently and it lasts long enough for weekends. No water clouding, which is a big plus.
William Mills –
Great for bottom feeders like my Algae Eater. The Spirulina chunks are visible and the fish seem to enjoy the texture. Lasted about 10 days in my tank.
Justin Ellison –
My Redtail Shark has been eating this block regularly. It’s convenient for when I’m away, and the fish don’t seem stressed during feeding breaks.
Blake McDonald –
The block releases food slowly and keeps the fish fed without overfeeding. Works well in a well-filtered saltwater tank.
