Guest Mike and Linda Posted December 17, 2010 Share Posted December 17, 2010 I have a glass top and was just curious if I should leave it closed all the time or leave it half open? What would be better for the fish. I do heat my tank. 0 Quote Link to comment Share on other sites More sharing options...

Just make sure nothing and no one can get in the tank and if you heat it (why?) that you replace what evaporated, if it is more than the normal water changes would take care of. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member Sakura Posted December 17, 2010 Regular Member Share Posted December 17, 2010 Half open is better for the fish.

Guest Mike and Linda Posted December 17, 2010 Share Posted December 17, 2010 I heat so that the temp stays stable at 74 F. My temp in the room where the fish are goes from 66 to 71 on a daily basis. I don't have heat in that room. I read alot on here that the temp needs to be stable. I never use to use a heater. 0 Quote Link to comment Share on other sites More sharing options...

Regular Member number20121 Posted December 17, 2010 Regular Member Share Posted December 17, 2010 Oh ok! I thought you meant you are having the tank at a higher temperature. Sorry, I'm not awake yet. I'm doing the same thing as you, got the tank heater set to 72. Durrr. 0 Quote Link to comment Share on other sites More sharing options...
Guest Mike and Linda Posted December 17, 2010 Share Posted December 17, 2010 Would the half open hood apply also for Betta tank? 0 Quote Link to comment Share on other sites More sharing options...
