So, no major squabbles… I did witness my dominant reticulated throw a hissy fit when he met them ( big size difference... lizards are bigger ), but the lizards were undeterred... yesterday all 3 were in different spots in the aquarium, this morning, I got to witness some lizard contact / dancing, in a bubble waterfall, they were just side by side, a couple inches apart, and intermittently would slide over, and rub up on each other... it didn’t look like a territorial dispute, or full on mating… looked more like a “hey buddy, nice to see you” kind of thing… BTW, the dominant Reticulated was a foot away, on the same side, so it seems to have gotten over it... no aggression with the lizards towards any of the smaller Hillstreams...
I added some more Bacter A E last night, I think it’s beneficial to my biofilm eaters
They do look more like newts ( lizards ), than fish in the tanks… but these guys seem to prefer vertical, rather than horizontal… in fact the picture above, with the 3 on a leaf, is the only time I’ve seen one, not on the glass
