He is so little!
For how much ebjd cost this isn't a gamble I would have gone with.
I would add more cover in the tank. Give the little guy more hiding spots that as the oscar grows he can retreat to.
He was $19 Canadian, so $13USD? I got him a local bigals. He was in a tank with 10 others. He was one of the most colourful. There was another that was a bit bigger but he was aggresively chasing around his tankmates and I didn't want him.
I'm more concerned he dies later and then the oscar is left without a buddy. I originally wanted a red or gold severum but the LFS's didn't have any, so I just said screw it I'll gamble an EBJD.
I'm going to be moving them to a 90gal maybe next week. The 90gal was heavily planted but I removed a lot of the plants. It'll have a piece of driftwood, java fern, and a few other plants. They might rip them up when they get bigger but when they're small they can hide.
The tank also has a 4-5inch albino BN pleco and 5 adult cories. I'll monitor closely to see if the oscar seems to show any interest in eating the cories. Though they're the same size as him right now.
