So I just bought 50 lbs of Aquamax 500 carnivore floating pellets (a little bit smaller than a pea) for $30 and a 5lb bag of Aquamax Starter 300 fingerling floating and sinking pellets (bb size pellets) for $6. Great deal but this will be a long term thead to so the affects that it has on tropical fish. All of my smaller fish love the 300 except for my yellow lab, but he is still eating it eventually. Plus all of my larger fish seem to like the 500 heck even one of my motoros tried some, although she did spit it out after a few chews. The 300 should really help to put some weight on my smaller baby fish since it is 50% protein, the 500 on the other hand is only 32% (that number is off of memory i threw the packaging away). The onyl bad thing that I can see so far is that there is not a consistent ingredients list. They just get what they can so every batch has a different list, but they guarantee the nutrient levels in the food. So we will see if it works I am also trying to find the Aquamax 500 omnivore pellets but no one around me carries it.
