New member here and fairly new to the hobby as well. After reading the info here I've come to the conclusion that what was sold to me as C. julii
most probably are C. trilineatus. Can anyone confrim this?

I currently have 9 of them together with 12 Hemigrammus erythrozonus (don't know the english name though), 3 Anomalochromis thomasi and 1 Ancistrus sp. in a 150 litre aquarium.
Edit: sorry, just realized I posted in the wrong forum, can someone move this thread to the right place?
