Ok I try to answer all the questions!
4 gallon tank
Temperatur 76 F
Tank has a filter with low flow no airstone
the tank is heated
he has no mates in his new tank
before he lived with red cherry shrimp
he is a very finicky eater
pellets he refuses completely
betta buffet flakes
freeze dried bloodworms
1x weekly frozen bloodworms
due to he is a baby betta I feed him every day a small dose
I think some of his problems could be that he constantly is constipated.
He sometimes eats like a maniac and then he has problems and won't eat for days
I perform a weekly water change of 40%
I add to each change water safe Tetra fin
Alkalinity very low usually I have between 40 and 80 ppm but at the moment I have less then 20ppm
And it comes very low out of my faucet... I tested that as well...
This is a completely new thing....
maybe that is one of the problems I have going on..... How can I raise the PH and Hardness?
more oxygen? He hates a strong current!!!!!!!
Would an air stone help?
Thanks for your tipps in advance!
