I picked eels for one real reason and that is that water quality especially
dissolved oxygen content can be very low and they will still be ok. I keep
African chiclids which live in very hard alkaline water, like you would get in
the cisterns at WW but they need high oxygen levels as they are very active.
Osteoporosis in WW will be non existent :)
