This strange fuzz in on all food I put in my tank within a couple hours. Facts about the tank when this started:
* I put aquarium sand in my tank. Within a month the fish started dying and food started growing this stuff.
* I emptied tank and got rid of sand and cleaned tank and put in new rock and new decorations.
* I bought two puffer fish and put them into newly arranged tank by themselves with none of the old fish.
* Puffer food also starts growing this fuzz. Flake food, disk food, brine shrimp, blood worms. It all grows this fuzz. Puffers have both died.
It seems as though the fish stopped eating after a few days and then about a week later died. I don't know what this stuff is or what to do?? Anyone help??
First set up was for a year, second set up has been running 2 weeks.
Fist set up had guppies only, second set up had green spotted puffers (small)
There are no live plants
Tank water is at 80 degrees
Using filter Top Fin 60
No CO2 unit
Tank gets natural sunlight part of the day
I performed last partial water change five days ago (half the water was changed)
I perform water changes every 7-10 days (partial)
I feed flake food twice daily and everyother three days I put a cube of frozen brine shimp or blood worms in (depending on guppies or puffers)
I use flourescent lighting. It is on approximately 9 hours a day
PH/Ammonia/Nitrate/Nitrites all fall within normal perameters at each testing. I use test tubes and liquid drops, not test strips.
The puffers were very active and healthy eaters in pet store and while in my community tank with other freshwater tropical fish (mollies, neons, danios, cat fish, guppies, in a 60 gallon) Once they were moved to their own tank to save the fins of my other fish they stopped eating and died like the guppies in the tank before them.
