Hi guys,

Ive had six rocket pencils who have been living peacefully in my 100 litre community tank for over a year now. But in the last week i have had 3 die :( they werent acting themselves, had gone from all hanging out mid tank to mostly being at the top and more so floating around.

The only change to the tank in the last month was the addition of 6 clown kilifish. Ive moved the remaining three into a nursery net but have not moved them to another tank for fear they may be sick,

Does anyone have any ideas? please help!!!
