Hey I've been reading that my columbian tetras may gain brighter colours from affecting the substrate. I currently have a light coloured sand which may be too bright for them? I wondered about adding leaf litter to break this up a bit for them - also I believe my corys will appreciate this.
What leaves are generally used and do I need to prep them in any way? Won't they just decay and create ammonia?
thanks for any help
