Expertise
I can answer all questions related to freshwater aquariums. If I am not available because I am maxed out, you can find me on the Aquarium Plants category. Fish care, fish behavior, feeding, breeding, and diseases are my specialty. To be specific, I am most familiar (though I am familiar with most species) with Livebearers, Tetras, Barbs, Danios, Loaches, Goldfish, Angelfish (freshwater), Catfish (corydoras, plecos, etc.), Bettas, shrimp, and even snails. I can help out with new tank setups, the cycling process (nitrogen cycle), acclimation of fish, and general care. I can also answer questions regarding many species of freshwater plants, including fish compatibility with plants. Additionally, I can lend a hand when it comes to aquarium support equipment questions, such as those regarding filters, heaters, lighting, and thermometers. Questions about aquarium water conditioners and products are also accepted. I will try to answer your question to the best of my abilities, and if I do not know an answer, I will do my best to find out. I do not have much experience in saltwater aquariums, or pressurized CO2 systems, so I cannot answer any such questions. Best wishes, and good luck to your fish!

Experience
I have kept freshwater fish tanks for many years, and I am experienced with a variety of different freshwater species and invertebrates, such as Tetras, Barbs, Loaches, Danios, Livebearers, Cichlids, Goldfish, Bettas, Catfish, Shrimp, and Snails. I have helped people set up aquariums, and I am very familiar with aquarium products and equipment. I have also bred many fish, and I always care for my fish in the best way possible. What makes a good home for tropical fish? Well, all tropical fish, like guppies and Bettas, require filters, heaters, and a good-sized tank. Healthy fish should be actively swimming and feeding, with defined fins and clear eyes. Take a random check of some of your fish daily, to make sure they're thriving!

Education/Credentials
I own an extensive collection of aquarium-related books and magazines, and have read all about, and I am experienced in, many aspects of humane and proper fishkeeping. Through these books and other articles, from reliable internet sources, and from personal experience with fish, I have a thorough knowledge of freshwater aquariums, fish, and freshwater plant species.
