nice oscars you got there.
What do you have in your tank? is it just 3 oscars and a pleco?
how big is your tank?
you may find that once 2 of your oscars pair up, the third 1 will have some problems (getting bullied)

Hi there, They are currently in a 60 while my custom 125 is being built. The 3 oscars and the pleco are all that is in there. I rescued the two large oscars about 2 weeks ago. The guy had both O's 3 plecos and about 18 feeders in a 30 gal tank. Needless to say they are now happy in the 60 and will be estatic with the 125. So far everyone gets along GREAT!

I like the way you said SO FAR everyone gets along great, because sorry for the news but 125 is not big enough for 3 oscars, they may seem ok now, but in time you'll come across alot of problems, if 2 of them pair off, the other 1 will get bullied.
It may work but it may not, so you may be running a risk, what filters do you have because 3 oscars and a pleco will produce alot of waste.

Thanks for the info I will keep that in mind! I am running 2 60 gal wisper filters and I keep up with my water changes.

Do you mind me asking what your water reading's are?

I have never checked them. I guess as long as everyone is active and eating they must be ok!

not always the case mate, things can happen over night and you wouldnt even know, its a good idea to get a water testing kit.
honestly, it could save your fishes life at some point.

I will do that! Please give breif discription an what it does, how to use it! All info is helpfull.! Thank you

american pharmaceuticals has a liquid master test kit that is quite easy to use and has very clear instruction with it. this is the brand i recommend and use. it cost about $30(at petsmart) but has enough reagent to last quite a long time.

also just curious but what kind of filter are youplanning on running on your 125?

Not quite sure yet on the filter! Any Ideas??? I will go and get the kit tomorrow! Thank You for the tip

for a 125 i would recommend a couple of fluval 405 canister filters. there are other brands that you can choose from like eheim, rena, ect. what you are looking for is enough filtration to handle a tank twice the size of the one you have. ei. if you have a 125 gallon aquarium you would want a combination of filters big enough to handle a 250 gallon tank.

hope this helps
