I noticed I started to have those brown/green hair algae growing on my live rocks, is it GHA ? Cyano ? Dino ? Can some of you experts please help me identify it and help with a solution? I have had my tank set up for about 6 month now.

Thanks.

Looks like all three. Welcome to the ugly stages. It means you are reefing.

HOW MUCH DOES A FISH’S FEEDING REQUIREMENTS AFFECT YOUR STOCKING DECISIONS?

  • A lot! - I avoid fish that require frequent or specialized feeding

    Votes: 12 28.6%

  • Quite a bit, but an automatic feeder can change my answer

    Votes: 6 14.3%

  • It depends on whether my nutrient export can handle it

    Votes: 6 14.3%

  • It depends on how badly I want the fish

    Votes: 10 23.8%

  • Not much. I’m willing to adjust my routine

    Votes: 9 21.4%

  • Not at all. Feeding demands don’t limit my stocking choices

    Votes: 8 19.0%

  • I usually learn about the demanding feeding schedule after buying the fish!

    Votes: 2 4.8%

  • I haven’t really considered this before
