I have a 20 gallon kribensis pair tank. I know the tank is small buy I would really like to add some more fish to the tank. I was thinking of 5 tiger barbs or any other fish that are aggressive enough to stay with the kribensis. Any thoughts?
-I have just got a pair in a 20g long and them have burrowed in the sand under rocks to hide...it has just been 3 days so far but they are sure timid...adding rocks to give additional hiding places...considering some dither fish if it will make them happier.
