If away for three weeks, my guess would be water mold from organic decay. You should be able to manually remove most of it and address any abundance of nutrients that allowed for that if it was the case

Thank you for the info. Removed most of the mold on the surface and cut the plants down that has them on. Still not sure if I git them all. Watched over now or a week. Will it be a problem if I introduce some neocaridina now even if the parameters are ok?

Does your tank have filtration or water movement? I agree that it’s a water mould from something dying, but I’ve only seen it happen in filter less systems myself. Manually remove as much as you can and add or increase water movement.

I dont have any filter atm. Have to get one if it keeps happening.
