You just got a male Betta fish yesterday It seems to be staying on the bottom of tank and not swimming around much Is something wrong?

There are a few possible reasons why your Betta fish is staying at the bottom of the tank and not swimming around much:

Water parameters: Bettas are sensitive to water quality, so it's important to make sure that the water in your tank is clean and free of toxins. Check the pH, temperature, and hardness of the water, and make any necessary adjustments.

Tank size: Bettas need at least a 5-gallon tank, but bigger is always better. If your tank is too small, it can cause stress and lead to health problems.

Hiding spots: Bettas need hiding spots to feel secure. Make sure there are plenty of plants or other decorations in your tank that your Betta can hide in.

Tank mates: Bettas can be territorial, so it's important to choose tank mates that are compatible with them. Some good tank mates for Bettas include snails, shrimp, and small peaceful fish.

Disease: If your Betta is sick, it may be lethargic and not want to swim around. Common Betta diseases include fin rot, dropsy, and swim bladder disease. If you suspect that your Betta is sick, it's important to quarantine it and treat it with medication.

If you've ruled out all of these possible causes and your Betta is still staying at the bottom of the tank, it's best to take it to a veterinarian for further diagnosis and treatment.
