1)- Use at least ½ gal jars, preferably 1 gal. The more the water the less the pollution.
2)- Do not let uneaten food rot in jar.
3)- Do not overfeed!!
4)- FULL water changes once a week. For 1/4 jars, full water changes every 3 days.
5)- Make sure clean water had same PH, TEMPERATURE than the old water.
6)- Use a digital thermometer or your finger to make sure the temperature of the water in the jar and the new water you will be replacing it with are the SAME.
7)- Do not use gravel. Worms hide in it and bettas can’t eat them later. Also uneaten food cannot be easily spotted and removed.
8)- A live plant is good, but only if it is healthy. A plant rotting will POLUTE the jar.
9)- Be gentle when handling bettas during water changes.
10)- Use soft net.
11)- Remember to not use the same net for healthy bettas and sick ones!!
12)- If a betta looks like it “may” be sick, do not use your healthy betta net to net him.
13)- Disinfect nets after each water changes (weekly). Use a solution of Formalin3 (by Kordon) or any other fish net disinfectant. Ask your local pet store to recommend a product and to tell you in what proportion you should mix it. Let your nets dip in there for a day. Then RINCE WELL and use again. I make a new solution every time I dip nets.
14)- Disinfect in the same way the jar of any betta suspected sick before using it for another betta.
15)- Wash your hands EVERY TIME you handle a sick fish or its jar.
16)- Last, but not least COVER YOUR JARS!!! Bettas do jump! You can use transparency sheet (for computers) to cover up to 6 jars at a time. It is easier at feeding time to have access to your jars that way.
