Thanks for your advice, bro. I am now considering if I would sell away the two exsisting small rays and just keep the big rays together with the arowana.

I used to keep 5 pcs of 8 to 9 inches PDR, 1 Xback and 1 Tig in a 3.5X2.5X2.5 ft cabinet tank with sump, change water twice a week about 20% each time, I can maintain zero ammonia and rays are ok.

I suggest you buy a test kit to check for ammonia and if you can keep it at lower than 0.5ppm, best if zero, it should be ok. You should monitor closely if you want to continue to keep those fishes listed in the same tank in the long run.

Will heed your advice and do more WC. Likewise, I might just sell away two of my smaller ray.


Thanks

I think you should sell the rays before they get bitten......

Just to share my recent experience.

Like wise I had MMs in a tub with 2 smaller motoros recently... last week the two smaller rays got bitten quite bad... torn disc and perfect tails become table tennis rackets.....had to transfer them to my aro tank... once they healed I guess I had to let them go sadly.....

HI all

Just an update of my ray collection.

I have finally house 1 x 15 inches MM, 1 x 12 inches otorogon SP, 1 x 6 inches SP and 1 X african arowana.
Thanks all for the advice.
