DawnE Posted May 4, 2022 Share Posted May 4, 2022 I glanced at my tank this evening. My 2 otos are super active, swimming back and forth, up and down, continuously. I have seen the swim around before, not just flit from plant to glass to plant etc., but not like this. Is this normal behaviour? Link to comment Share on other sites More sharing options...
xXInkedPhoenixX Posted May 4, 2022 Share Posted May 4, 2022 Hi @DawnE. Common Otos are much more active in the evenings and early mornings. So this just them doing their thing. The more you have the more natural this behavior would become (Otos are shoaling fish and do very well in bigger numbers). I have 70+ in my 20 gallon tank and they are always moving during the times I mentioned and pretty mellow during the day. Link to comment Share on other sites More sharing options...
