Expertise
I can answer any questions regarding a freshwater fish tanks such as, Filter (sponge, normal filtering, air powered small filter, canister, bio-stage filter or any other filter.) any water heater (bottom plate, bar heater, starting a new tank, cloud problems, or any other thermometer.), illness, disease/cure, bacteria growth, algae problems, breeding, information on any fish, behavior issues or anything that may come across as weird behavior, ceramic bubblers or normal bubblers, air systems, suggestions of fish to get, method on breeding, water condition, medications, conditioners, foods, or any other question that you may have. Also have all the information on the tank setup that you may need for specific fish. (for example Oscars are messy fish so you should have lots of filteration.)

Experience
I have three tanks of my own. One is a ten U.S. gallon tank; another is a thirty U.S. gallon tank, as well as a 1 U.S. gallon tank. There are four other ones that are not mine but I take care of. I also take multiple classes on freshwater fish. In that class we learn about the newest diseases and anything elts like that. I do attend informational meeting at some different schools. I attend aquaculture currently. In this there is 12 200 gallon tanks that as a class we take care of.
