So far there are no cordies suffering such problem, but there are a couple cordies that show minor sign of trying to regain control over their losing equilibrium too. But their tails tend to float rather than sink like the guppies.

anyone experienced b4 pls teach d best & effective way to prevent this kind of sickness.. and how to cure the sick ones coz I have one in quarantine still.
