Its a 34 uk gallon tank thats 39 inches long.
I had 4 females and they all got on well so decided to get 6 more but when I saw all the females Joby had i just couldnt decide so went for all 11, so now I have 15.
Yesterday they had to sort themselves out as to who was boss and pick out a bit of tank for themselves and today there is no aggression, very little flaring and chasing and all come out to feed.
If at any time I see any that might be struggling I have the two foot tank that can take them.
Here is a pic of the tank they are in.
Theres plenty of hidey holes and lots of plants to hide in as well. I only ever see half a dozen out at a time unless its feeding time when they are all out, but so far so good.
