I have just been away for a couple of days and 1 of my guppies is looking very bloated.
The 2 other guppies and 7 Harlequins and 3 shrimp look fine.
It is a 90L planted tank and the guppies have been in the tank for about 2 months along with the shrimp, the Harlequins have been in about 6 weeks.
I don't think i am over feeding and they have not had food for a day.
Water temp is 26 degrees C, and all water parameters are very good and where they should be, only maybe the high Ph at 8.2 is high. Other parameters:
pH acidity 7.6
There doesn't appear to be any sighs of this on the other fish, and the one that is bloated was the biggest of them all, oh and they are all males.
Any help greatly appreciated.
