Hi guys,
Just thought I would give the official 3 week update. The fish are now 5-6 weeks old and I am still having major nitrite issues. I am doin frequent water changes to keep them under control but it is time consuming! I have also bought them a Medo Air Pump (pricey but they're worth it... I hope ;-) ) which is pumping 40lpm as opposed to 5lpm. This is intended to create stronger current to get them swimming harder and in a few weeks I will pop the filter outlet in the pond to create a heavy flow to really get them swimming!
Sadly I lost the runt fish, which was lovingly called 'banana fish' because he appeared to have a small amount of lordosis lol!
Anyway, here's the little guys today
