Stuck? No.Did you see a difference in growth? Do small fish get stuck?
I only see a different on the plant on the left only...
correct because that is the side where it is concentrated at. Water Sprites really love Co2, in any amounts. It went from a mid-level plant to reaching the top of my tank in 1 week. You might not see this type of result say with Vals, or Anubias or otheres. But with sprites they LOVE IT.
