Every so often I see two of my Balas an theyll be swimming right along side each other, but it look like there hitting each other with there heads. Is this a common thing, are they fighting, Mating??????
ihob78 said:Bala sharks are one of the more passive freshwater sharks. They do best in groups of three or more as they prefer to school in an aquarium. Even though they are one of the more passive sharks they are still semi aggressive. Unfortunately, the breeding habits of the Bala Shark have not been documented.
Also, the bala shark requires somewhat of a large tank to be comfortable prefferably with lots of rocks, wood, vegetation, ect...
Since they prefer to school I highly doubt that they are fighting over territory. If infact they are fighting though you may want to take tank size into consideration. I recommend 70g or larger. If they are male/female you could be witnessing some sort of courting/mating ritual. The other thing you may want to consider is they are simply playing with each other.
In any case I wouldn't worry about it unless it gets worse, a fish gets injured or it appears that one of them is being bullied by the other.
turtall said:Good size tank for them, they do grow large. We have three, so far, in our 150 and two of them have been doing the same 'dance' they were doing in the 75. Usually after a good feed. Seems to be non aggression, more like the ritual ihob78 mentioned.
