Shmowgen Posted June 11, 2021 Share Posted June 11, 2021 I hate creating these posts. I have a 20 gal tank that had a diatom algae overload. I got two Otos to help manage it and maintain a clean tank. 2 weeks ago one Oto died unexpectantly and I just found my other one dead this morning. My water levels have stayed pretty consistent and I try to check their stomachs to see if they are nice and full but after the first one died, I noticed that the remaining Oto was hiding a lot more which made sense. But it made it difficult to see if he's been eating. I'm trying to look for factors that could affect this. Lack of food could be one of them. It's possible they weren't eating (even though there is algae in the tank but maybe not what they liked). This worries me because I have a Siamese Algae Eater as well and I really dont want anything to happen to it. The only other thing I am noticing is my ph is a little high (7.6 on "low ph test and 7.4 on high ph test). My water from the sink is at around 6.8 so something in the tank is causing it to rise, I think. Everything else for my water is really good. Which is frustrating because I do my best to keep my water great for the fish. I just don't know what else could have caused them to die all of the sudden. Thanks for the help/advice.
