Good morning everyone. I have 3 Hemycianea and 1 Hexatenia in my 60"x20"x20" (100 gallon) aquarium... I added 3 more Hemycianea and they were massacred by the first 3... Now... Since even 3 are fine for me (I just wanted to increase the number and give more color and movement to the aquarium) I wanted to ask you: will every small catch of another species be chased and disturbed until exhaustion, or will the other species be tolerated and ignore? Thank you
