What type of fish is this?

  • We are currently upgrading MFK. thanks! -neo
I know I’m late to the party, but I agree that’s 100% a juvenile jd.
Mine at 0.5 inches:

Maybe not as interactive as an Oscar, but grow up to look just as good:

My brother went to Petco and got a fish who was sold as an Oscar who'll be in a 125 gallon tank but the longer he's had the fish(4 days now), the less he says it looks like one. Do you all have any good guesses as to what type of fish my brother might have? I figured this was the best place to ask :) Thank youView attachment 1474331, View attachment 1474331View attachment 1474328View attachment 1474329View attachment 1474330View attachment 1474331View attachment 1474330, View attachment 1474328View attachment 1474329
It's a JD. Would make a cool tank with it being the central "FISH" with some large tetras - white skirt/balck skirt/albino Buenos Aires as dithers. Add some natural sand and fake plants with driftwood and you'll have a spectacular tank.

..puSkar.. ..puSkar.. maybe. My male JD would eat every one of those fish within a couple weeks. My male currently lives in a 150 with a texas.

My Jack is mellow, but he’s never had a taste of dominance. So far he hasn’t tried to eat anyone, but the dithers are still huge next to him, only one I’m afraid of is my female krib, but still got some size and knows how to hide.
I’m afraid of what he’ll do in a few inches though.
 
With any cichlid, aggression attitudes change with age.
Maturity can make a seemingly docile cichlid change almost over night, and kill tank mates.
Just because it has been docile for 6 months or a year, does not mean it will remain that way tomorrow.
Another factor is tank size.
A JD (or any medium size cichlid) may be less aggressive in a 6 ft tank, than in a 4 ft tank..
JDs are not piscivores like Parachromis, they are omnivores, yet even that can be influenced by tank size.
Any dither fish that can be easily cornered, due to lack of tank size, is at risk of being exploited as a protein source.
In nature, JDs are surrounded by live bearers like mollies, and gambusia, but in nature the number of gallons is in the thousands,
Expecting them to live peacefully together in a tank of only 50 gallons long term, is being a bit overly optimistic.
JDs and mollies living relatively comparably in nature in a video below.
