I strongly disagree with this comment. Never put an Oscar in a 30 gallon tank, unless you have no feelings for the creature and don't mind its suffering. Adamzieger, actually if you first buy a 30 gallon tank, and then a 55 gallon tank ... you're spending more money than you should. Because if you buy a 55 gallon tank in the first place, you do not waste your money. Besides, it's not just about the money. Think about the health and happiness of the creature which you're intending to keep in too small a tank for it.adamzieger said:I say go for it man, Half the stuff Fish people tell you is a lie to get you to buy more stuff, Ive broke pretty much every ruel you can think of that has to do with fish, and all my fish are alive and nice active. Just do what you want and if you need to upgrade up from the 29 once it gets larger do so and get a new fish in the old tank.
Jim, that was uneccessary. We are all entitled to our opinions even if we disagree. I have found that there is not much absolute on how to keep fish, but I do try and help those new in the hobby to learn from my experiences so they don't make the same mistakes.JI'm said:I deleted my other replies to this thread. I have evey reason to believe what Isabella and Gunnie say. They've been VERY helpful to me, and I hope I didn't steer you wrong. I do think a SMALL oscar would be ok, but what Isabellla said is VERY true, you'll be buying another, much bigger, tank before you know it, and unless that's you're planning to do anyway, it's a HUGE waste of money.
I have read that over and over on these tropical fish boards, and from friends I've met online that I trust completely with the health of my fish!PPK9110 said:i've always known that fish can only grow as big as to establish their tank size, but I didn't know that their inside still grow...interesting..where you learn that, just curious
AMEN ! ( lol )Gunnie said:We only want what's best for your fish, so if we tell you putting an oscar in a 29 gallon tank is not a good idea, you are certainly within your rights to do so, but you're not going to hear that it's okay on FishLore if it isn't, and if anyone says it is, then there will be debate. I will tell you why I think it's a bad idea, and will leave it at that. I currently have 2 oscars about 3 years old in a 100 gallon tank along with a common pleco, and I sometimes feel that they need a bigger tank. They are both near a foot long and are still growing. The pleco is over a foot long. Yes, they can swim back and forth in the tank, but they only have 5 feet in length to swim. They are also enormous waste producers along with my pleco, and can mess up a tank in no time! Good tank maintenance is vital in their health. I do at least a 50% water change in my tank every week, or the nitrates go sky high. Mine seem pretty content, but I wonder sometimes if I should get a bigger tank.
I'm sure you've heard that a fish will only grow to the size of the tank. That is a myth. His body on the outside might stop growing, but his insides continue to grow. This is a very slow and cruel death for a fish. Stunting a fish's growth is not something we advocate here on FishLore just because we don't want anyone mad at us. You will see us recommend that buy fish that are suitable for the tank they will live in as adults. You can certainly keep healthy fish and move them to bigger tanks as they grow, but we don't recommend it here, because there is a chance that you will not get that future tank because something not planned on happens, and then you have a fish in too small of a tank.
Oscars can also live 10 years if taken care of. That's a big responsibility and committment on your part. Plan on buying fish to keep for their lifetimes, just like you would a dog or a cat. They are also quite grumpy, and as they get older and bigger, they tolerate less and less. My two fight contantly, and sometimes I'm just about ready to move one of them because I don't want serious injury. The one that picks the fights is always the loser, and has had plugs taken out of him more than once. You will have a hard time putting any other fish in the tank with your oscar, so keep that in mind also that you will probably resign yourself to that one fish in your tank. They also like to rearrange their tanks to their liking, so you will probably not be able to have any live plants in your tank, and any decorations should be very sturdy because they will be attacked and moved around.
I know you just asked a couple of questions, so please don't take my post as gettin on to you about the questions. We are all here to learn and share our experiences, and your questions are encouraged, and show a genuine concern on what fish you should have, and how to take care of them properly. I think a pair of angels in your 29 gallon tank would be much more suitable. They can be quite personable fish if you give them attention. Mine line up like good little soldiers when they think it's feeding time, and would probably eat out of my hand if I trained them. If you want more aggressive fish, I don't think it would be hard to find some that would do well in that tank. Convicts might be a species to consider. They are cheap, readily available, but breed like rabbits.
