Do you have an Oscar fish that lays on the bottom of the tank sometimes? Does your Oscar fish seem to sleep on the bottom? Does your Oscar pout in the corner if you have to mess with stuff inside the tank? Why does my Oscar fish lay on the bottom? If you’ve ever asked any of those questions, we’ve got some answers for you.
For starters it is not a cause for concern and in most cases this is perfectly normal. The Oscar fish is quite temperamental and sometimes they just pout. Mine will lay in the corner if I have to move stuff inside the tank, almost every time. If you leave for a few minutes and come back, he is usually back up and swimming around. If your Oscar lays on the bottom for days on end this could be the sign of a problem though, so check your water parameters if that is the case.
It is not uncommon for them to rest on the bottom from time to time. They may do it because of stress, it is really hard to say. Mine will sometimes take a bit of a rest on the bottom after a big feeding session as well. So, many factors can contribute to an Oscar resting on the bottom but in most cases it is nothing to worry about. As long as it isn’t for days on end and the fish is still active and eating an occasional rest on the bottom is not cause for concern. If you are concerned it doesn’t hurt to run a water test to make sure all the parameters are good, as long as they are your Oscar should live a long and healthy life.
