New fish (need advice)

[Kevin Greif]

hey i got 2 jack dempseys today on my trip to the lfs and when i got them home i was wondering if i could put one in each of my larger tanks or if i should keep them together in a smaller tank. keep in mind they are 3 inches, and both of the larger tanks have one 5 inch oscar.. so it would be two 40g. with a 5 inch oscar and a 3 inch jack. OR i could keep the jacks together in a 20g. untill they are larger.

thanks for the help

at 3" they should be ok in the 20g for a few weeks, but they can become aggressive toward each other at any time as they grow. Just keep an eye on them, one may have to go in one of the oscar tanks.
