Hi all,
I've got a small 5.5 gallon tank in my cubicle at work, with a crowntail betta and a emerald green cory. (I used to have two cories, but one succumbed to fin rot
).
Anyway - I have a real problem with algae growth. I scrape it all clean, and within a few days it's back. It's the brownish-green algae that sticks to the glass. I have a problem with it at home, too, but I'll save that for a different post.
I've let it go for a week or so now, this time - been busy at work - and I've noticed that the algae has started to disappear in the middle. Are my fishes eating the algae?
And if so - should I just leave it there for them instead of always scraping it off? Is it harmful to the fish to have too much algae or is it just unsightly for us who want to have a pretty tank?
I attached a picture of the tank so you can see what I mean - the brown algae with the "eaten away" looking part in the middle.
