OTHER REASONS CAUSING FIN ROT OR SPLIT FINS
Frequent water changes will cause stress on your Betta. Water changes shouldn’t be more than 50%, recommended 25% to remove any uneaten food and debris. Please keep up with water changes at only 25%, give them a decent tank size, don’t overfeed, or overcrow your tanks. Keep their homes as clean as you would keep yours.
CONTINUOUS TAIL BITING; WHY THEY DO IT?
Most tail biting occurs during shipping. In the dark, Bettas can confuse their tails and bite thinking it’s another Betta in front of them. Tails do grow.
Other reasons could be from seeing Bettas next to them, their reflection on glass or mirrors, stress from illnesses such as internal parasites, or from hormones released in the water by Bettas kept in the same tank.
When purchasing Aquatic Decorations, please avoid anything with sharp edges that could cause your Betta fins to rip.
A more natural environment is recommended such as live plans, rocks, and driftwood to mimic their environment as closely as possible. For ideas, you can Google Aquascape.
