I have a 32 gallon tank with 4 tiger barbs, 3 green tigers, and 2 cory cats. I wanted to add an Agassiz to it but was not sure if I can just add one or if I should add more. I was wanting to also possible add a red tail shark at the same time. My tiger barbs are on the smaller side still so I’d like to get them all added when they are the same size to help since they are known as semi-aggressive fish. Any tips on adding Agassiz would be great!!
