hi guys,
on page 148 of diana's book,
it said that ...ponds with only floating plant often have decreased oxygen levels...
but i put 2xguppy(or 2xtetra, 3xshrimp..) in a 700cc plastic cup noly with water and many floating plants(Pistia stratiotes) , the fish do not show any different (no wheezing).and i do 100% water change everyday, find the fish can live in such environment for many days.
why?
