1 fat oscar 1 skinny oscar

[bicboihulk]

hi, new to the hobby and i have a problem with one of my oscars. so i have an oscar that would eat everything i put in the tank and is growing huge! well...compared to the other oscar at least. both are still juvis bought from different lfs around the same size. my problem is the other one barely eats, if i do see it put food in its mouth it will spit it out. it will barely swallow any pellets i give him. i just recently got them for like a month and it seems like one is getting so fat and the other one is getting skinny. my big lutino is about 4 inches but fat and the black tiger is 2.5 inches but skinny.

Have you tried different foods? I've had picky eaters before... Oscars are usually gluttons though

Tank size? Have you tested the water?

sounds like you have an aggressor, this stresses out the the other oscar as he is afraid to compeat to eat.

it's a 75 gallon with eheim 2215 and i just added a aquaclear 110 hob filter

Probably bit small for 2 oscars. Not a lot of room for the less dominant to get away. 75 is stretching the limits for one O really.

i've been pretty diligent in my water changes so far, about 20-25% every 3-4 days. the lfs said it should be okay and i've seen people with more oscars before. back the main topic, the black tiger does eat, but it seemed like it wasn't eating enough. he looks the same size since i bought him and the other grew significantly. i usually do a small feeding before i go to work and a small feeding after work. only on mondays during my day off i'll do a third feeding. i have them on hikari staple pellets, is their another pellet that is good? i don't want to feed live items, i don't like touching insects and people told me fishes have diseases.

Hikari is fine as a staple mate. I've seen 5 crammed into a 75 before and kept 2 in same size when I was a teenager but would go a little bit bigger if doing it again. I def think it's either a dominance thing or you may have a runt. Any pics mate?

a dominance issue would be my first suspicions, the best solution long term would be to do one oscar anyway; so I'd return the runt and focus on the lutino imo
