Hello All,
first post here. Looks like a great forum.
I have kept aquariums for 20 years on and off. Saltwater, fresh, planted, crystal and pinto shrimp, etc. However, I am new to guppies.
I bought some breeders a trio. Both females and male have died. Lots of fry from two successful births are alive and growing well in grow out tanks. The trio died at different times. Water parameters are all zero. Sometimes nitrates are 5-10 but many times zero as I have lots of plants.
I believe I might be overfeeding because in every instance the fish look like they have a swim bladder issue and die hours later. The last one was the male. I fed the tank kinda heavy. Left for the gym came back and he was swimming upside down. I put him in methylene blue and he died within the hour. All others died in similar fashion.
Thoughts?
