Infusoria (a menage of one-celled or equally teeny multi-celled animals) get their name because they originate from vegetable infusions – pulverized vegetation in water. Why Use it? : Aquarists feed infusoria to their tiniest fish fry. Example, gouramis start life too small to eat most foods. Even newly hatched brine shrimps are too big for gourami fry. (Betta fry are a little more aggressive in that some will rip the legs off newly hatched shrimp.) If you intend to rear the smaller egglayers (including bettas), you will need infusoria. Starting Instructions: Make an infusion by boiling hay or grass in water and using the cooled “tea.” One rabbit food pellet per jar is about the same thing. Other infusoria growers blenderize lettuce leaves. Some just grab a handful of aquarium plants and squeeze the juice (and infusoria) from them. In other words, you can invent your own formula. Add this to six quart jars half-filled with aquarium water. Let stand in an out-of-the-way place for several days. (Window sills in the sun can get too hot.) You will need about a week to determine whether your cultures are a success. Set aside a gallon of aged water for later use. Tap water contains chemicals designed to kill infusoria. For some strange reason, humans prefer to consume water with less nutrition in it. Select Your Best Culture: Shine a penlight through your water. Look for “dusty-looking water.” Those dust-size particles are your infusoria. (Infusoria also make cloudy water in new tanks.) Not every culture establishes itself at the same rate. Pick your best culture and clean out the others. Start new cultures and inoculate them with your most successful culture. (If you use plastic or opaque containers, you cannot check which of your cultures are successful.) Selective breeding at its finest. Or you can start 100 cultures and grade them on the curve.
