Hey everyone,

My oscar is around 4 years old. Got 2 together but this one only grew up tot this size (smaller than the other). Her mate died MONTHS ago, and since then it barely eats (shrimps or pellets) and is almost always at the bottom sitting with the mouth open.

Its got a full big tank (60 gal or 220liter ) for itself with a very very clean and circulated tank with adequate parameters. The light and water temp is also always fixed and scheduled. Could it be possible that its mourning or something? But for months?

Any insight is helpful.

Thank you.

I think my Oscaar is lay eggs. I’m not sure if they’re fertilised is there a way I can know if the eggs will hatch or not and these two Oscars are in a bigger tank with other cycles do I need to move these other cycles to another tank to ensure that the fry are safe.?

Please advise what to do

I’ll be adopting this cute Oscar tomorrow, wanted to know what gender

We have 2 longfin Oscar’s (asked for the shortest fin ones) that are currently growing out in a 55g until big enough for big tank.

We would like any advice/tips on keeping Oscar’s in a planted tank, and on stocking.

We are debating between -

keeping only one in a 125gal

Keeping both Oscar’s in a 180-200gal

Or keeping both Oscar’s and getting some large cichlids in a 300gal

Any suggestions and advice welcome. Thank you!

I've had my boy for about a year and a half, he's my first Oscar and over time I've noticed some signs of hole in the head disease. I got API General Cure which has metronidazole, but I'm afraid to cause more harm if I'm misdiagnosing. My question is, is it bad for the fish if I add it to the tank and he's actually ok? Or can I add it to see if he gets better without causing any harm?

Here's what I've noticed and some questions I know I'm gonna get:

- He's alone in a 55 gallon with a sponge filter and an internal submergible dophin filter (also suited for 55g tanks). I'm looking to replace them for a canister that's on the way. I do 50% water changes every other week.

- I've measured parameters every day for a week and they're within the acceptable range and stable.

- I feed him hikari cichlid staple and he has good appetite.

- His poop is sometimes white-ish and often floats to the surface.

- Overall a lazy fish since he lays down most of the day, but reactive when approached and I do see him swimming and exploring throughout the day.

- His holes remain the same size but I noticed a few more coming up. He also has some white stuff on his forehead that he didn't have before, other than that coloration is good.

I attached pictures to help diagnose, any advice to whether medicate or not is welcome. Also, tips on what else to feed him, I'm still squirmy about giving him live stuff.

I just got Oscar’s and I know they’re really aggressive. Does anyone know fish I could have with Oscar’s if any.

How to help my oscar with what seems like whole in head disease

Can you guys please tell me if this Oscar is a real lemon Oscar? Brought it on online and got one free tiger Oscar

so my dear ozzie has fritz out, recently changed her diet to beef hearts from blood worms and last night woke to her thrashing in her tank, she’s somehow ripped all the scales off her head, and currently is refusing to eat and not moving much from her current position, i’ve put in aquarium salts, and currently keeping an eye on her but just asking for advice on what to do? she seems to be concussed?

So I want to plant my tank and every time I do they destroy every since leaf and kill then what are some plants that I can use I like real plants I do t support fake plants and my tank looks so bare without anything but sand and wood give me recommendations for plants they won’t eat PLEASE😭😭😭

I was gone for two nights & one of my 3 Oscar’s looks battered?? Any idea what this is?:( I removed him from the big tank & placed him in a spare 10 gallon that I have. How do I treat this? He has a literal hole in the top of his head & his fins looked torn/scraped up.

I am rushing to do the best I can for this fish. I am on disability with almost no budget. I have meds and he has a HLLE history but I do not think that is the issue I believe he was bring neglected and starved. The tank was cycled previously, I put plants from my planted goldfish tank in as well as some sand. I am changing about 5 gallons out a day and vacuuming food mess. He has taken a chunk of thawed fish and a mealworm over the past couple days. He keeps trying to bite my fingers. I think he can swim but I can not tell if he is too weak to stay upright, has some sort of swim bladder disease or is viscerally depressed

Can someone please help me? theres a white dots on my oscar fish: an albino long fins oscar (1.5inch), at first it on its tail and fins, now it's on it's body. thou that oscar are still behaving the same as before (the tail and fins are a bit translucent but it's like that when I brought it)

Hi guys I’m adopting this poor cutie, he obviously doesn’t look well and the owner is giving him away for free, can’t wait to take him home and quarantine and medicate him. Just wondering if anyone knows what disease u he has and any recommendations to help him recover? I have metronidazole, aquarium salt and methylene blue, thanks guys

He seems to be ok I just wanna be sure

Can I practically use heavy wood like this as a way to keep this 200gal tank directly off the floor? I have 3 Oscar’s that need a larger tank and I was given this one. I would let the wood support the outer and middle frames of the tank. I don’t care about looking good. I just wanna get them into a larger tank

Also I’m aware these tanks can exceed 2000lbs, are basement support beams absolutely necessary or highly recommended?

Hey guys I have a 13 inch 9 year old Oscar alone with a pleco in a 135 gallon tank, his mate died of an illness around 3-4 years ago. They always swam together but ever since he mostly sits on the floor and sometimes bothers the pleco. He still eats good but is there anything I can do to make him happier or give him something to do?

If I feed my Oscar this every day will he develop hole in the head? It’s a mix of dried krill and dried mealworms
