When keeping freshwater shrimp, it's essential that you feed them food that is appropriate for them. Shrimp (unlike humans) are not content with eating 2-3 meals a day - in fact they are quite the opposite and graze constantly. As soon as they have finished what they are eating, they're off to find more food. Ultimately this is what makes them ideal for use in the planted aquarium where algae can often be found.
With many tanks though, there isn't enough algae to keep them sustained particularly if your breeding colony of shrimp in increasing in numbers and as a result you have to supplement their diet. This is a good idea anyway as algae is OK for them, but it doesn't contain everything they need.
Genchem Biomax is a unique shrimp food in the respect that it has been designed for 3 different sized shrimp.
Size 1 is suitable for baby shrimp as the pellet size is very small and can be handled easily by these young shrimp. It's really important to feed baby shrimp more regularly than adult shrimp, especially when they are very young. If they do not have sufficient food regularly then can easily die. Don't over feed this product but underfeed either.
Size 2 is suitable for juvenile shrimp - I would consider these 4-8mm in size. The pellet size of this food is larger than Size 1 and as a result is more attractive to shrimp of an appropriate size.
Size 3 is for adult shrimp - this food is the largest out of all 3 and ideal for shrimp of 10mm and upwards. This food contains selected nutrients which will also encourage breeding.
By using all 3 sizes of Genchem Biomax in your shrimp tank you will ensure that all of your shrimp feed on appropriateate sized food and also get the best nutrition.
