Well if he could just chill with your females it might make it easier on you but seeing as how rare that is a new tank/bigger tank divided might be the better choice but you can use the breeder as a place to keep him till option A or B comes in
I think im going to have to divide my 25litre my other male is in for the time being.
My halfmoon male Thai will be moving from his tank soon to breed so I can look to dividing it then. hopefully
And then look for bigger tank for the 2 of them.
I just missed out on a 60litre on Friday night aswell
