    As the title says: how does tank design effect fish behaviour and aggression?
    My tank is peninsula style between kitchen and living room so always have something to watch. They all get along happily, with very little aggression towards each other.
    When i go away i do not employ a tank sitter so the glass gets covered in algae. Not cleaning for three weeks and you can barely see into the tank so obviously the fish cant see out. I noticed it a few times that when i return from holiday to dirty glass, the fish (especially brisstletooth tang) are super aggressive and the tangs will most likely have cuts on them.
    Once the glass is cleaned the fighting stops immediately. Has anyone else noticed this behaviour?

    So cute, they missed you :lol:
    I haven't noticed the same with my tank however I have seen that the inner glass starts to get mirror like when algae builds up and causes the fish to go ballistic fighting with their reflections. Could it be the same for yours?

    My algae build up skips the mirror like part.
