Hey Everyone, just trying to figure out what went wrong with my puffer. He was about 5 inches and had him for the past 2 months. Had him in a 75 gallon tank until he got bigger. In this tank all he had was a big piece of drift wood/fake plants and sand. His water changes was very few days about 25% mainly to vacuum out food. His filtration is 2 Seachem tidal 75s. The water parameters at his depth was the following: He pretty much ate Krill everyday, then suddenly seemed not interested then died less than 24 hours later.

Ammonia 0
Nitrite 0
Nitrates 20
PH 6.0
Temperature 78-80

So far I think it was the either the PH being at 6 because of the driftwood. I used to try and keep it at 7, but was told consistency is more important so decided to leave it where it naturally would sit at. Or possibly oxygen maybe? I don’t run an air bubbler and rely solely on the surface agitation from the Seachem filters.

What do you guys think?
 
I think there was a swing in the PH and caused the death of the Fahaka Puffer. Sorry for the loss.
I have had the driftwood in here for over a year, but few months with the puffer. Think a ph swing could still occur? Figured it would have been stable at 6.0, but idk.
