My biggest harlequin rasbora won't let any other rasbora into the left side of the aquarium. It's a 29 gallon tank and there's currently 6 rasboras in total. This has been happening for a while, though this stopped temporarily after installing my aquaclear 70 to the tank earlier this month, it started again today. At one point there was a school of 9 though those deaths were a while ago, except one. Last Thursday, I found one of my rasboras dried up on the ground, I tested the water after that occurrence and the water was fine. Now the tank has a glass top so that can't happen anymore. Anyways, do you have any ideas on why this is happening.
