My problem is that all of them are fighting, they go out of their way to get into a fight with each other, its like they all really like the left side of the tank and the are all fighting for that side of the tank, and I'm pretty sure there is 1 male and 2 females. I know this is normal, for them to fight to establish dominance, but i thought it would only last a day at most. When they engage, they circle, go vertical while circling, return to horizontal, curl their body and one charges and the other usually swims off, but since this morning, they are actually striking each other, sometimes whole 2 are engaging, one comes out of no where and takes a sucker punch on one of the others, I'm starting to get worried... is this typical Dwarf puffer behavior for them to fight for dominance for this length of time, its been 3 days since i got them.
Where they always seem to fight, is the only part of the tank that is open for swimming, so the only thing i can think of is to put a plant in that area..? Here is a pic of my tank. It seems like they are fighting on the most extreme left front to mid tank, where those 2 shorter plants are.
