I came back into the office this morning and saw there is some kind of white buildup on some of my rocks that formed over the weekend. Have never seen this before. Any idea what it could be? Screenshot 2025-07-28 at 9.24.10 AM.png

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

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

    Votes: 16 32.7%

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

    Votes: 6 12.2%

  • It depends on whether my nutrient export can handle it

    Votes: 7 14.3%

  • It depends on how badly I want the fish

    Votes: 11 22.4%

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

    Votes: 9 18.4%

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

    Votes: 8 16.3%

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

    Votes: 2 4.1%

  • I haven’t really considered this before

    Votes: 4 8.2%

  • Something else (see my comments in the thread)
