Looks like diatom algae. It’s completely normal in a brand new tank (happens to just about every new set up) and should disappear once the tank cycles and everything stabilizes
well, I was planning on having a larger school of Lemon Tetra (Originally with the Congo) but NOW *cough* @Tony s *cough*... Im not sure anymore
But.. I keep going back and forth between Congos and Diamonds.
I’m sticking with Diamonds😂 that’s my final answer… maybe…
only issue with Congo is only the males are showy and they get bought unsexed😞
good thing I have a black background and black substrate
Yeah, Lemon tetra have been my top choice for awhile… but I’m easily distracted when it comes to Tetra… I always see “a cool new shiny” one that makes me rethink my choice 😂
