l bought two used tanks, fish and all, a 30 & 60 gal freshwater tanks. The red Wagtail Platts in my 60 gal tank are 'fighting' to get in the lower part of 2 corners. The have been acting like this going on three days. Temp is 74°f, all levels are in the healthy range. 20% or so water change Saturday. In process of changing filter as we speak. Is this behavior indicative of a problem?
