Arowana does not allow smaller one to eat.

Dear All

I am Ankur Lakhesh from India and have recently bought 2 Silver Arowanas for the first time.

I am really enjoying these elegant creatures as a part of my home but am a bit concerned about their behavior.

One of my Arowana is around 11" and another one is about 10". They swim around the tank whole day and seem very friendly toward one another but while feeding, the bigger one becomes very aggressive and does not allow the smaller Arowana to eat. The smaller one gets forced into a corner while the bigger one eats and even after he is done eating, he does not allow the smaller one to come on surface for feeding.

I have read a lot of posts on this site and I am sure that the current tank (24 Gallons (US)) is not sufficient for them in longer run, I will be definitely upgrading to a 150 gallons tank in a few months (Waiting to move into my new apartment), but am not sure if this is the only reason for such aggression because for the entire day they keep swimming around with peace.

Please advise what can I do to keep them at peace till then.

Thanks in advance
Ankur Lakhesh

The current tank is 3Ft X 1 Ft X 1.5 FT

hmmmm.... thanks for the response. but that does not feel possible as I do not have enough space for an additional tank :-(

The tank dimensions are 36 X 12 X 15 inches and comes around 28 Gallons.

What I have read on this site till now is that the tank size needs to be 3 times in length and around 1.5 or 2 times in width of the Arowana, so technically I think this tank is almost suitably sized as of today.... Please correct me if I am wrong..... I will be getting a new tank in 3-4 months time.... would love to get a new one tomorrow, but would be moving in 3 months time to a new house, and would need to shift the entire setup again which is pretty risky... (Indian road conditions).... also, what I have been told, for setting up a new tank we need to run a new tank for at least a couple of days before adding the fish.... So I will b stuck while shifting cos there wont be an interim arrangement available :-(

Again... I am new to this.... do let me know if my information is incorrect and suggest what can be done for this period of 3-4 months... may b adding any other fish to DISTRACT the bigger arowana or something else.....
