hi! I would like if someone help me with this: i have a 54 Liters aquarium and i would like to know if i can put there 3 charax gibbosus? I have there a couple of kribensis and a L260
54L seems quite a bit to small of a tank, If you go with a larger tank then they do prefer to be kept in small groups rather than alone so 3-5 is a good number. Remember that they are quite sensitive to temperature fluctations and tend to get ich if chilled.
100/40/40 has the same ground-messurement as my prefered 200 Liters, seems to be enough.
Information is rare... they like to be keeps in shools as said and they're told to be the little version of the biger characins... eats little neon-sized fish.
can't tell you if they bite biger fish' fins.
