How to clean your tank if your betta is sick.
![]() |
Well it is not much different cleaning your tank then you normally do. Well so I will tell you how to do it.
First you get the fish into another tank (or some where you can keep it for a how ever long it takes for you to clean your tank.) Once that is over empty the tanks water out in a sink (make sure NO rocks fall out if they do put them back in the tank.) Then you get a strainer (or something similar) to dump your rocks in and run HOT water though them (to kill all the bacteria in the rocks) once that is done (NOTE: make sure all the water that is falling out of the holes is CLEAR water not even a tad bit dirty). Now we must was the tank grab a cloth and put HOT water on on the cloth then wash the tank with the cloth. If you use artificial plants just run them under HOT water. If you use real plants put new ones in the tank. Now put your rocks and plants in as you normally would do but fill the tank with your normal water (can be bottled water) in make sure it is purified. Then put your betta in the tank and give him his medication. Hope this helps,

Hey Sam, I clean my 2.5 gallon every two weeks, is this okay?? I’ve never gone more than three weeks without a water change, I try to do it more often.

This is great advice, and really, cleaning using this method should be done for regular water changes. To completely sanitaze your betta’s tank you should rinse the tank with bleach and hot water, and dry it with a cloth. Set the tank outside in the sun to dry, as this will ensure that the bleach and its chemicals are gone. Bake any substrate, such as gravel, on a cookie sheet in the oven at about 300 degrees. This will kill all bacteria. Throw away all live plants and any other decor and replace with new. Now, you’re betta tank is completely clean and safe.

Hello everyone, decided to search for abit of insight from the professionals
I currently have 3 crown tailed betta fish (all males) in three seperate tanks. I clean out the tanks once a week, replenish and change the water with britta at the same time and clean it as if they were sick just for the sakes of being thorough, I also use the appropriate water conditioners and water clarifiers. Also being very meticulous about the water temp as well which is between 24 and 27 celcius(yes I’m Canadian lol)
So far two of them are doing extremely well but the third (which i have read from previous posts) seems to have conditions of staying to the surface and tilts to the side. He appears to not be eating well. I will try fasting him for a few days and see what happens.
My question is am I doing this the right way or can anyone point out a better way of going about this?

I was told that when you change water for any fish, it is better to leave about 20% of old water in the bowl/tank so the fish won’t get too stressed. My betta got some bacteria eating his fin and I will be treating it while it’s not too late. There is nothing in the bowl besides a heater and a stainless steel thermometer. I thought removing dirty part of the water from the bottom using syphon (tube) , and cleaning sides of the bowl with sea sponge while the fish is in was enough, but apparently it was not.

Now, if I change water completely, do I need to leave some of the old one in? Then keep treating water daily, would that help? I really don’t feel comfortable put better in a completely new water. I’ve heard it can die from such change.
