currently i have 3 ottos in my 16gal, there is more than enough algae in the tank
i was just wondering if i would need to add more for them to be happy or not,
also was wondering do they eat cucumber, just incase i run out of algae?

thanks for any replies

i dont find they eat cucumber . They graze algae of plants etc more than glass, you really want 4+ ottos for a shoal.
but it would depend what you had in there and if there will be enough algae?

they will also eat pumpkin, zuchini and most other fruits. It is a good idea to blanch (soak in boiling hot water for a few seconds) the fruit beforehand, and remove the uneaten food within a few hours to prevent it fouling the water.

Hi I have 7 at the moment and through much trial & error found that algae wafers soaked in tank water for 5 mins and stuck to the inside of the front of the tank works great they love them and all except one hangs around at night time. They all have big bellies now. They seem to fight over the waffers its great to watch.
