Ur NGT is just unstable. Some are just likethis.
Stuck with it and over the months and
Years, maybe weeks... it may remain stable at other times other than waterchanges.
That's the way with tigers. There's no quickfire guarantee method to make them
Stable and make Them Stay stable.
Yeah. Its very thick, is growing nicely as it pounds massivore. There is still is contrast between the yellow and black bars most of the time...its not all dark but it is rarely as "neon" yellow as it looks in the photo. My 10" 3 bar IT is stable 99.9% of the time, even though it get punked by the NGT.
