    No, your tank won't be large enough. Recommended is 100 gallon for 1 adult Oscar.

    Becareful with the Arowanna. They get big and will eat anyting they can get a hold of. They will out grow that tank quickly.

    Get rid of the arowana on one of the oscars and you will be fine.
  • Jeremy Roche - 2012-11-16
    The arawana would be pushing it.  This would work while they are all small but these fish get large and the Arowana  get very long.

i bought one wild oscar(4inches) to my tank. it was very active when saw in the shop. but it is not active when i introduced into my tank. it is staying always at bottom of the tank for over 7 days. when i am feeding him earthworms, he is ok. but later settling down again at bottom. what should i do to made him active?

    Oscars will do this when they are introduced to new surroundings.  The stress of the change will go away and it will begin to swim around more.  Water quality close to the same as tank it was removed from?
  • j.stephen - 2013-01-05
    i really dont know sir. is there any problem because of this? if so, what should i do?
  • Jeremy Roche - 2013-01-05
    Oscar will adapt easily.  If you start with temp and pH close to same it is an easier transition, but doesnt have to be.

    They are just like people, they will grow differently.  If they are both eating, they are fine.

  • Jeremy Roche - 2012-05-29
    With a 6 foot tank you have a ton of options. I would stay away from Arowanas and large fish like that. Really depends on what you are looking for.

    Cichlids are a good one or kilifish I don't know saltwater can be good to like butterflyfish & saltwater betta -40 gallon for mature size

hey, i have had two of these guys for a while (2 monthsish) and they live with a little blue gill, they are the same size and get along, but i noticed awhile ago that the two different species of fish looked very similar all though they are two different species that live on different contenents, also they seem to have the same body structure as other members of the cichlid family. could it maybe be possible that the blue gill is some kind of cold water cichlid?

    They will need to be over 14 months and around 10 inches. Are yours there yet?

Does anyone know any details on black blotches on an albino oscars face? When I look it up it says check the pH levels, and Ive seen the strips before but if it is messed up how do I fix it. I have a 3 year old oscar, got him in july so I am farely new at this but his tail has a bit of black and his fins and he has black splotches on his face and forehead area. And also does anyone know what levels I should be testing? Thank you. Ive been learning as I go.

    Your Oscar has head rot. Happens alot with Oscars. It's caused by too much activated carbon in the filter, poor diet, or lack of water changes.
  • Jeremy Roche - 2012-04-14
    get a multi test kit and test all levels. there are drops that can be used to increase or decrease. How often are you doing water changes?

Hi, I am getting a 150 gallon tank that will have( and I meen will) 1 red bellie pacu, 3 senegal bichirs, 4 firemouth cichlids, and a pleco. I was wondering if I could put 3 or 4 oscars in there to keep the pacu away from the other fish. the pacu is owned by my science teacher and has unfortuenetaly gotten a like for meat but I would like to teach it to eat fruits and vegis so it will be less likely to hurt the other fish.P.S.,should I put the pacu in first or the other fish starting with the least agressive ones so they can establish teritory?

    You can do what you wish but doutfull more than one of these fish will survive. Tank is way too small. You have carnivores in there and if it will fit in their mouth it will be food.
  • Shawn Handley Jr. - 2012-04-09
    I could put in the pacu last so all of the less aqqressive fish can establish a territory and mabye even keep the pacu in check. Though I would rather recommend a green terror instead of a oscar (I own one they are very smart and in my opinion looks more smart than a oscar which also grows I think 3 inches longer). Though I think a green terror would keep the pac in check though that is my opinion and you should still check with the experts to see what fish would be the best.
  • Jeremy Roche - 2012-04-10
    Before you can get an accurate answer I would need to know the size of each. There more then likely won't be room for the oscars. These fish all grow pretty large. With the group you have I would put pacu last.

I Have 3 Oscars 6 inch, 3 Convicts 2 inch, 3 Jacks 3 inch , 2 Catfish 2 inch, 2 Red Belly Pacu 4 inch, 1 Red Devil 5 inch, Puffer Fish 2.5 inch, 2 Crawfish, and 1 Blue Lobster 3 inch. They get along for the most part but the Red Devil screws around with the red belly Pacus a lot and 2 of my Oscars have a white dandriff on there Pectoral Fins. I can't figure out what it is. If anyone knows please let me know, I would appreciate it!

    Sounds like you have a big tank! Starting off with your Red Devil. Very interesting and pretty aggressive fish. Shouldn't have too much too worry about it as long as you have a good bit of hiding places but keep an eye out, he could hurt your Red Belly Pacu! As for your Oscar's,hopefully I got to you in time, really does sound like the first stage of Ick. They have medication for it, not that much maybe $4.oo. Or if they were in the same batch from the same breeder, could be a marking. But, treat it as Ich. If they get to their second stage, 2000 hosts will attach themselves to your other fish and get them sick. But,unfortunately it usually takes till the second stage for all Ick treatments to be effective. Try Ick Clear Tank Buddies. I used it on the first stage and it worked. Hopefully I helped!

    I had 2 tiger oscars. I had them for about 3 years and we are just now getting another one he or she is really big but right now it is not going so well. See they have ick which is a very bad disease that kills the oscars. Very easy for them to get. And right now we are doing all we can to help them.
  • Anonymous - 2010-03-31
    Is the white ich?
  • Ashley - 2011-07-26
    I had an albino tiger oscar and one regular tiger oscar for 9 or so months. They both started developing the "white dandruff" on their pectoral, dorsal, and tail fins. I assumed it was Ick and treated them for that but when it didnt work I tried treating them for bacteria, infections, and parasites. But the white spots just seemed to multiply and eventually covered most of their bodies. Nothing worked and they died within 3 to 4 weeks.
  • ron lovell - 2011-07-29
    How big is fish tank? Trying to set up freshwater in a 60 gal. Just bought 2 oscars, 1 red devil, and 1 blood parrott. How many do you think i should get? Recently thought about taking oscar back. I think they are going to get too big for tank.
  • Liam McEwan - 2011-08-15
    This white dandruff stuff is a sign of the fins decaying. Be sure to ad methelyn blue to your water and some fin rot prevention medicine.
  • Liam McEwan - 2011-08-15
    Ich or whitespot treatment should do the trick.
  • chrissy st jules - 2011-10-04
    Its ich. You need to go to the pet store and get drops REAL quick or it could get to the other fish
