100% new to discus besides knowing how they look. I am currently working on initiated and fixing up my 55 which is running into some troubles, so this probably won't happen for 2-6 months. I was wondering how many discus could fit in a 10g, I was hoping 2 (I don't know discus average full grown size) or if one or non can fit in a 10, than numbers for a 20 and 29 would be nice. Also do discus have any special requirements? Thanks!
