Hey so my first aquarium I started 4 months ago about. It's doing great! 80 gallon freshwater aquarium. I have a ton of fish rn because my fish are having babies upon babies upon babies. I have dalmatian Molly's white sail fin molly rainbow sharks plecos galore 2 different cichlids. Just added a blue lobster and fire eel and guppies and danios. Ordered ghost shrimp. Anyway what does it mean when your gourami switches from colors? I had 2 1 went missing before I got the eel and lobster btw. It wasnt doing so good tho. It was either stolen since it stayed a darker blue and then other one has well a mark on half its head I named him Harvey dent. Anyway Harvey changes color slot from dark blue with darker stripes to a pale blue and everything in between. No clue what this means and I thought it was my other gourami when he was darker but figured out it was still him when I saw the change before my eyes.
