Freshwater Aquarium/Expert Profile

Ask A Question


I can answer questions about betta, goldfish, aquatic snails, freshwater crustaceans, freshwater bottom feeders, and tropical fish. I have little knowledge on freshwater frogs/tadpoles. No saltwater fish/cichlids questions please! I do *NOT* know how to make Decor for tanks/aquariums. I can also help you if your fish is stress/sick and setting up an aquarium/fish bowl/tank/etc. I can also help you with disease/injuries/parasites/etc. I can also help you with compatibility of tropical aquatic animals.

Experience in the area

I have 30+ years of experience with tropical fishes & bettas. If you have a question (sending a picture will help) just ask and I will reply as soon as possible!


I went to Stanford University (Graduated). Has a Masters Degree
