You have 3 goldfish how often should you clean the 1.5 gallon tank?

You should never put 3 goldfish in a 1.5-gallon tank. That's incredibly overcrowded and cruel to the fish.

Here's why:

* Goldfish get big: Goldfish can grow to be surprisingly large, and they need a lot of space to swim and thrive.

* Waste buildup: Three goldfish in such a small tank will produce a huge amount of waste, quickly polluting the water and making them sick.

* Ammonia poisoning: Ammonia levels will spike rapidly in a small tank, leading to ammonia poisoning which can be fatal.

Here's what you should do instead:

* Choose a larger tank: A minimum of 10 gallons is recommended for a single goldfish, and you need even more space for multiple fish.

* Proper filtration: Invest in a good filter that can handle the bioload of the fish you have.

* Regular water changes: Even with a filter, you'll need to do partial water changes at least once a week to maintain water quality.

Remember, your goldfish deserve a healthy and happy environment. Don't compromise their well-being for convenience.
