I got hundreds of Bettas. Every morning wake-up feed fishes. It took me about 30mins to feed them all... up down left right front back, everywhere bettas.
All my bettas are outdoor, so i facing algae problem. Changing water is a big headache. Hundreds of tank i have to change weekly!!!
I'm force to cover all the tanks with cloth.
From now i gonna setup an aquarium for my bettas indoor.
A system that don't have to change water so often & only 1 tank. Combine all bettas in a tank with only 1 filter system.
