The tank is 100 litres or 26G (US). Plenty of room for more. I could add some more CPDs, but thing is, I am trying to keep Nitrates down. The tank is under stocked at the moment as you can see. My tap water is 40ppm Nitrate and so I have started buying RO
(which I reconstitute myself) from the LFS
. The more fish I have, the more trips to the LFS
to keep the Nitrate down.
I have Rotala Macrandra, Rotala Wallichii and HC growing which like soft water with low Nitrates see.
That is my dilemma. You are right though, CPD's lampeye's and ET's all like to be in skools of at least 6-7. Not sure what to do really
