Thank you very much for your answer!
Luckily, i do have an other tank, although it ll take enough time to be prepared, as there is no equipment on it ( it will take a while to save the money to purchase all that is needed :wink: )!
I think i m gonna wait though for the other tank to be prepared so that they ll have the propper environment!
The second tank is 22g, what number of fish do you think would be suitable for this volume?
