Hello,

I recently set up a community tank with a few arowanas and bichirs

-Silver 6 inches
-Austrailian 3 inches
-Ornate bichir 6 inches
-Endi bichir 5 inches
-Albino bichir 5 inches

The tank is fully cycled and parameters are decent. The tank is 120g.

History: The fish have been brought together for about 2 weeks now. There is no aggression between any of the fish what so ever. The fish are eating. The Australian is the most lively and eats like a champ. Food is plentiful.

Incident: I came home last night and found my Australian missing one eye. It appears completely dug out. I have no ideas on how this is possible. He is still alive and swimming around. I plan on separating him tonight from the other fish until he gets healthier. After the incident, all fish still appear to be eating.

Possible explanations:
- He got spooked and swam into a piece of drift wood
- He was attacked by other fish....

Any ideas for the community on how this is possible?
 
Arowanas need to be kept as one arowana with other tankmates not being arowana or in groups of three or more. from my experience keeping two will only result in one getiing beaten up and eventually killed.
 
One of the bichir's plucked it... My now 11 " Senagal pluck an eyeball from my now 11" agro albino oscar. This happened a long time ago when my oscar was only 2-2 1/2" and sen was ~8-9". As long as your fish is already healthy it will be fine, but will have one heluva hunting blindspot!

I've watch them wait till something is close and they strike like a snake at anything that darts in front of them and possibly edible. And eyeball is a delicacy in many parts of the world! >_<
 
Thanks for the input. I have separated the Aussy. Do you recommend adding him back into the community after he is older?
 
I would not put him back once either of the Jardinis rEACH ABOUT 8". I have had 3 differant ones and no combination worked in my 260g tank for the 2 of them. They would just fight each other, i had a silver arero with them at the time which was 24" and they just ignored him and attacked each other until scales (large ones) were flying in tank and I had to seperate.

My P Afer Knife(18") is like that- as long as the fish in its tank is big enough not to be picked on- it was a 'fishmate'... But put the any 2 together, or a cichlid in with the knife- someones dieing!
