Hi all,
I am currently facing an issue of my fish remaining hidden at the back of the tank during the CO2 and Light period from 11am-7pm. I don't think it's the light brightness as some forums suggest as I keep it on a pretty dim setting (lower light intensity than the fish shop I purchased the fish from anyway!).
I know that injecting CO2 can cause the pH to drop so would it be possible that the pH drop is causing the fish to become lethargic and 'hover' at the back of the tank. They don't sit on the substrate, they seem to just float in one space, in the dark areas at the back of the tank.
The temperature of the water is set at 25C (approx. 77F) and can fluctuate ever so slightly 24.5-25.5C. I don't think it's the temperature of the water either. In addition to this, when the lights are off and the CO2 is off, the fish do occasionally come out of hiding regularly but not as often as normal.
I do not have any test kits to test pH or KH or anything like that. The tank is fully cycled (as in, it's been set up for months, with an overpowered filter) and I have been keeping fish and plants for years. It's just odd behaviour that I have recently experienced. I'm not sure if it's been going on for longer that I think as I work all day weekdays and I'm barely home at the weekends so it could be an issue that's being going on for a while.
Filter flow is quite strong but the fish I keep are Neon and Ember Tetras - I'm sure they love good flow. Shrimps are acting fine. Also, my oto's and pygmy corys do hide as well.
Shall I test my water and see what I get?
It's weird because I haven't changed my processes - i.e. EI dose, feed the same food, water changes weekly etc. I can't pinpoint the issue at all.
Any help would be great,
Thanks,
Dan
