They are mainly night dwellers and if you have a heavily planted tank they rather stay in the plants in the shaded places.. I have dimmable lights and go about 5 to 10 % light intensity in the evening, just enough to clearly see what's going on in there. Oto's are more active during that time and show them selfs all around more often.. I also observed, for a while i grew the rotala (colorata) without trimming it and let a lot of it spread over the surface.. The Oto's loved it hanging around and feasting together in that bush just bellow the surface. Since i'm trimming this rotala down again i do not see this behaivor anymore.I can't work out what's going on with my Otos.
No longer than 24 hours.. What's not eaten will only rot away and pollute the water..How long should I leave the veg in tank before it needs removing?
Yes i have 8 of them realy lovely little fish swinging like bumblebees neatly flapping their fins like crazy. The denser the planting becomes, the less i see them. Well i know where they hang out, they are almost always all together laying around in the same corner, lazy little buggers. Sometimes 2 or 3 together come out, school alittle bit around with the tetra's and then disapear again in the forest.. Nicest cory i ever had..Noticed my pygmy corydoras spend more time mid water at night than during the day, even though my tank is low light.
