Hi. I've now had my Betta, Max, for a few months and before Christmas, I bought him a new 10 gallon tank, an upgrade from his previous 3 gallon tank. Last week, I decided to add 4 Corydoras (2 Albino and 2 Peppered), with the intention of adding a Bristlenose Plec in the near future. The Corydoras have settled in very quickly and were soon going about their business. Unfortunately, Max has taken a disliking to his new tank mates and is now constantly chasing them. For some reason, he appears to be leaving the Albinos alone and concentrating his efforts on the Peppered (which are slightly bigger).
After searching the internet for ideas, I found a possible solution; take Max out and either place in him a temporary tank or in a breeding trap for 1-2 weeks. Before releasing him back into the tank, change the layout of the tank to make him think he is no longer in his territory.
Does anyone have any views on this or any other ideas that I can explore please?
