Thanks. I am honestly impressed, never considered this could not be algae.

Light wise, I’ve been using the night light (blue lights) throughout the day for a week, it looks like it halted growth but I’m not sure.

The nutrient input is probably over feeding. I honestly don’t even think I give my fish too much food, just a pinch in the morning, but they seem not interested in the food and simply don’t eat it all, so most sink down and stay there. So maybe I should change the food type? Not sure. Also definitely feed less.

Is this harmful for the fish? I just had 3 little one born tonight and I’m worried about their health and all other fish too.

I’ve been thinking to do a remake in my tank especially the substrate that I don’t like so much, want to replace with sand, so I could actually use the opportunity and completely empty the tank except for the fish and water, get a better filter, leave it like that for a week and then start over. Is this a good idea?

Thanks all for all your insights!

Can’t wait to add this to my transitions blue light filter colour blind prescription smart glasses.

I’ve been waiting for years for this to finally be approved. I can’t stand Daylight Saving Time, only serves to make me tired for the next month while I adjust, twice per year. It’s a relic from the past and many countries are moving towards removing it or have removed it already altogether.
