I picked up a baby tiger oscar yesterday for my 90gal. He's sitting alone in a cycled 10gal right now. First thing he did was eat all the ramshorns off the glass lol. He's about 1-1.5inches long, very tiny.

I saw EBJD for about $15 at the LFS. They told me they get them from a local breeder, I don't have much more info than that. They are only about 1inch long. Will the oscar outgrow the EBJD enough that he'd just eat the EBJD as a snack? Is this a terrible idea? Alternatively I can get a 3-4inch EBJD but they're $50.. steep price.

I was also considering a gold severum instead but that blue colour on the EBJD is just so enticing.

I guess I could get both a baby gold severum and baby ebjd. If one of them doesn't make it I'll still have a tank mate for the oscar. If both of them get to juvie size and I get an overstocked tank I can look for a new home for the gold severum.

Ideas?
 
You would have a better chance raising them about the same size. Whatever you decide do not get the bigger EBJD because it will probably kill the little Oscar.

Ended up getting a baby EBJD. He's about 1inch. The oscar is 1.5inches in length but twice his size. So far they're just huddled behind the airstone together.

Last night they spent the night hiding behind each other near the airstone. With the oscar still being a pig and just inching out far enough to get food then swimming back. This morning the oscar was up at the top of the tank begging for food. I put some food in but the baby EBJD seemed interested but only managed to eat 1 pellet in the time that the oscar ate maybe 15. No aggression, he just was more shy about getting the food.

The EBJD seemed to eat really slow. He put one 1mm pellet in his mouth and seemed to chew for quite a while. These are Northfin 1mm pellets. I mixed the veggie and community pellet together to give some vegetable matter in their diet. Is there maybe something else I should feed them? Some sort of freeze dried food? I don't want to use live because of parasite risk.

Well there was 1 cherry shrimp in that tank I couldn't net out before adding them. Pretty sure the oscar ate it because I don't see it hiding anymore.

Freeze-dried Mysis shrimp.
 
Do I soak it before feeding? Any tips on getting the EBJD to eat more before the greedy oscar swallows it all?


No soaking required. As for the EBJD if its eating thats good. I would just observe at feeding time that EBJD is getting something wouldn't want you to jeopardize water quality over feeding.
