Male guppy bloated & sick Molly.
Hi, I have a male guppy that's been bloated, looks like a ballon, for the last three days now. He hasn't been swimming much nor eating and just sits at the bottom of the tank. He is in a tank with several other fish that don't show these signs. How can I make him get better? And does anyone know what's wrong? Also the condition of the tank is perfect, water has been changed and conditioned and ph is perfect.
I should mention too that I also have a Molly in the tank who has been acting odd but only at night, swims with what seems like a bent tail with head down tail up downwards in a spiral motion, I have had this happen to another Molly before which soon after died so am a bit worried, any advice on what to do for both fish would be great.
