I hate to do this as I am new to this forum and don't want to get a reputation. I am however very experienced in keeping cichlids and been an active member in other forums for years now. I also have years of educations as I am a doctor and majored in premed and minored in biochemistry. So I can in all confidence say that AquaPishFimp is completely wrong! Not just in most of what he has said in this post but in a few others I have seen on this site over the last few days.

You state that:

"Any fish will stop growing at a certain point in smaller aquariums or if they are fed a different type of food."

Of course a fish will stop growing at a certain point when you are feeding it a diet that is deficient or lacking the proper biological building blocks needed for proper growth. After years of evolution these animals are adapted to become fish that require high protein diets. When you deprive them of the key protein building blocks of course they will not grow as large. It is clear that by no means is a fish that you say only got to be 6" after years a healthy fish if they naturally grow to be 12+".

Just because most fish in the hobby are now generations from being wild species does not change the environmental and dietary requirements for this fish. It is true that these factors can influence the genetic expression of these fish, but by no means should anyone advice taking that to an extreme. What you are doing shows your lack of responsibility and respect for others on this site, the fish they care for, and the hobby as a whole. Not to mention you are clearly just someone who enjoys picking fights on this forum by arguing with practices that are very wildly excepted throughout the hobby. It is clear that you would not admit being wrong on this matter anyways.

I truly hope that the OP and anybody else reading this or post like it would go with the mainstream advice for care for fish like these. And not take the advice of somebody that is just obviously trying to get attention.

Improper diet? So your saying that vegetables are bad for you? The only reason oscars get big is because of fatty meat foods. Big doesn't mean healthy. All your fish must be overfed meat eating pigs that won't live long. Your seriously need to learn about fish. By the way get your facts right oscars eat nuts more than anything in the wild.


you should read more closely next time. The predator both he and I was referring to a was a Red devil in a 20. Not the Oscar. He was using the 7" Devil as an excuse for it to be ok to house the O in a 30

vegetables are far from bad for you and if you must know, I don't feed any of my fish meats at all. Tthey are actually on a pellet exclusive diet which includes plenty of vegetables and proteins sources.

learn to read and then you can feel free to debate the issues. This thread isn't about diet anyways. It's about tank size. And maybe you should get your facts right because eating nuts in the wild, an Oscar will grow larger than 7" which is what this discussion is about in the first place.

Feed your Ocscar cupcakes,green beans or dog food for all I care. Keeping one in a 30 gallon tank is cruel and I don't nee to know much about fish to know that
 
I know what your trying to say. But how would an oscar know the feeling of a bigger tank? He was raised in a 30 his whole life, which means he wouldn't even know what a bigger tank is. Just like your daughter example, she wont know whats out of the closet or even if there is anything out there. So fish will adjust to their surrounding and will live in it to stay alive no problem.

Don't take this serious but how do we know that fish don't like small tanks? I have seen red devils live together peacefully in 20 gallons.


It really depends on you, and how you feel about housing a fish in a smaller tank.


Thanks for that example cichlidsrock47

your absolutely right. The Oscar has no choice but to accept his environment and its the fish keepers job to provide one that is appropriate. and IMO 30 gallons is not enough.

think about it this way. There is a major difference between "Thrive" and "survive". Its the fish keepers job to know the difference. I could keep an Oscar alive in a ziplock bag changing the water twice a day. Doesn't make it right or advisable. vegan theory applied or not

You are completely wrong.

As I said, vegetables are not a fat food. Which means they will not grow much.
After generations and generations baby oscars will adapt to conditions in captivity.

The difference? 12'' or 6-7''. I personally would rather have a smaller oscar than a bigger oscar because less food and smaller tank.
I am not trying to pick fights, I am sharing my personal opinion.

I saw what I did. I kept those two oscars under the same conditions but different foods. Explain why a smaller oscar that was fed vegetarian foods lived longer than the oscar who ate meaty foods?

My responsibility? Is great, I saved plenty of cichlids from petsmart and petco.

I stick with my own opinion not others. I like to lead, not follow.
 
@Jc1119

You are telling us your opinion. Which can be agreed or disagreed. You said "I think it is cruel keeping an oscar". I don't.

how do we know if any fish like small or large tanks? If a fish was raised in a small fish tank how would they know what is a large fish tank if they never lived in one? Now that is a fact.

AquaPishFimp is a very knowledgeable fish keeper IMO.
 
^^ that s like saying I'll be sure to malnourish my kids so I don't have to buy new clothes or food so often. lol Like I said before the logic is baffling. I won't provide something so I don't have to provide something else. Makes no sense to me and that is my opinion......

I know every one is entitled to your opinion around here, but you're giving some bad advice based on 2 fish fed different diets. Do the dame test with 20 fish and average the results before claiming results. Real controlled testing. Splitting hairs over vegan or meat based diets what not the question anyways...it's about tank size and your using experimental feeding techniques to give out strange advise to make it seem ok......

if you want a smaller fish, buy a smaller fish. Don't try to make one because it's husbandry requirements are inconvenient for you to accept.

I find your opinion :thumbsdow.

aquafishpimps opinion is :thumbsup:.

a very knowledgeable fish keeper would not recommend keeping an Oscar in a 30 gallon tank or stunting it's growth to do so. Yes that is my opinion and it's also many other peoples as well........


read the original thread title. "Can an Oscar live in a 30 gallon for life". Of course the answer is yes, but it is not advisable......
 
Aquapishfimp is right. Almost everything was right. Except, oscar do eat meat in the wild but that does not matter because all our fish are from fish farms.

I'm not saying a 30 gallon is good sized tank for an oscar but it wouldn't hurt to keep one in it. With a diet of vegetables.

If a cichlid never lived in a large tank, it obviously doesn't know what it is. Cichlids are nature, and will survive in that tank. Possibly even be happy because we don't know their feelings only they do. Too bad fish don't talk:cry:
