Hi! My name is David, and I'm new to the forum. I currently have 2 tanks- a 7 gallon housing a Betta, 4 Cardinal Tetra, 2 Cory Catfish, and a few Amano Shrimp. The other one is a 3 gallon housing my other betta. Please give me any advice for fishkeeping as my dad is out of town and he's usually the one who teaches me about fish things. Thanks!
