Recently i have added 2 spotted gars about 6" in my tank. I have one silver arowana(8"), One Texas(8"),two oscars(6" & 4") in the same tank. I had 2 arguses before. But they always try 2 bite my other fishes fins specially my 2 gars. They damaged their fins so badly so finally i had 2 remove them from my tank. I used 2 feed all my fishes live guppies. But the problem is during feeding time my gars r having very difficult time 2 find it's food. Though i put lots of guppies in my tank but my other fishes finish them so quickly that there is hardly any guppy remains for my gars. And also my silver aro sometimes trying 2 bite my gars. What i need 2 do now? Plz help me guys.
