Cyclops passed away during the night unexplained.A 50% had been performed yesterday evening he was dead this morning.He had been off color yet on sunday he was fine.
Test Results Taken this morning after Dysons removal due to him being odd way Cyclops was.
pH 7.6 (best I have ever had)
Ammonia 0
Nitrite 0
Nitrate 0
Filters
Fluval 3+
Fluval 2+
Tank
30 Gallon just 2 fish
no new fish
Tank been running for over a year
Weekly water changes,King British Safe Water and Safe Guard water conditioners.King British Goldfish Flakes.
Unusual Findings
Fish lethargic not as active however appetite normal.
Noticed Filter media had turned a blood red color-so suspecting gravel is part of problem
A ornament that was also introduced to tank has strange growth on it.Plan on getting microscope to look at it.
This ornament was introduced a few weeks prior to Chance (Lionhead) and Piranha (Dojo Loach) behaving odd.Now Cyclops life has been taken.
Dyson was lethargic this morning but since removal and being put in established tank he has picked up and is more himself.
Due to color of filter media and odd growth on ornament I have reason to believe toxins at are being released from both gravel an that ornament.
The tank is to be stripped totally gravel ornaments disposed off.
Any ideas please as I am aware the cycle had also crashed reason I dont know as its never been a problem before.
