Ok I have been doing a bit of looking around online. This is what I came up with. Nothing is set in stone though. Just getting an idea.
German Blue Ram
Temp 72-79ºF , Ph 5.0-7.0 , Max 3"
Bolivian Ram
Temp 72-79ºF , Ph 6.5-7.5 , Max 3"
German Gold Ram
Temp 72-79ºF , Ph 5.0-7.0 , Max 3"
Kribensis Cichlid
Temp 72-82ºF , Ph 6.0-8.0 , Max 4"
Gold Veil Angel
Temp 75-82ºF , Ph 5.8-7.0 , Max 6"
Flame Dwarf Gourami
Temp 72-82ºF , Ph 6.0-7.5 , Max 2"
Redtail Shark
Temp 72-79ºF , Ph 6.5-7.5 , Max 4"
Neon Tetra
Temp 68-74ºF , Ph 5.0-7.0 , Max 2"
African Butterfly
Temp 75-86ºF , Ph 6.9-7.1 , Max 4"
Sharkskin Barb
Temp 73-82ºF , Ph 5.5-7.0 , Max 2"
Rosy Barb
Temp 74-79ºF , Ph 6.0-7.0 , Max 6"
Just from those looks like to keep all the fish happy I would need to keep.
Temp at around 75ºF
Ph at around 6.9-7.0 (butterfly makes it a higher minimum)
No butterfly the ph would be around 6.5-7.0
What are your opinions on this list?
