Will this work?

Question
QUESTION: Hey i am trying to come up with a stocking list for my 55g with 2 hagen aquaclear 110s ( 1000GPH )

This is my very ideal list:
1 Oscar
X# of Bala sharks
X# of Clown loaches

The min tank size for all of those fish is 55g and sometimes people say 20g for the Clown loaches ( underrated )and remember my filtration

ANSWER: Hi David,
An Oscar needs a 55 gallon tank all to himself.  Bala Sharks grow very big, and should be kept in 120 gallon tank.  I'm sorry to bring you such bad news, but these are the facts.  An Oscar, or other big fish that are kept in tanks too small for them will get very sick.  Their growth will be stunted, and their internal organs will have no place to grow, causing a terrible death.  When we keep an Oscar, we must go by the rule.  One Oscar needs at least a 55 gallon tank, two Oscars we must double this, and so on.  You have good filtration, and this is very good when keeping an Oscar, but it does not give a fish more room to swim, and be happy.  Vendors do not tell you this, they are there to sell, and couldn't care less.  They never take back an Oscar once he has grown, and you are stuck with the consequences, and sadness of losing them to a disease which is impossible to cure.  We get so attached to our fish, I would not advise you to stock your 55 gallon with these big fish, unless you keep just one Oscar.  Oscars are so very intelligent, and make wonderful pets.  We take them from their home to put into ours, the least we can do is try to give them a nice place to live.  There are many other smaller fish you could buy if one fish does not interest you, and you would like a community tank.  This is up to you.
I hope you will think this over very carefully, and that this information will help.

QUESTION: Could i just get an oscar and and some clown loaches, i know most a lot of places say they get like 16" but thats in the wild, at home they get a mere 6-8".

Answer
Hi David,
Clown loaches would not do well with an Oscar.  Oscars grow very rapidly, while the little clown loaches take more time to grow.  The Oscar would eventually see them as a good lunch!  The clown loaches like a sandy bottom, and the Oscars loves to redecorate his tank, moving rocks, and decorations.  The clown loaches need space too, the longer the tank, the better, so no, I'm sorry, I wouldn't advise you to add any fish with an Oscar in a 55 gallon tank.  He really needs all of this space to himself.  I know it is hard to be content with just one fish, but believe me, Oscars are so friendly, and intelligent, you would get so attached to it, that you would not mind he be alone.  However, like I mentioned to you, there are many other fish that are pretty, that you could put into your tank if you really want a community tank.  
You have a nice tank, with good filtration, this the Oscar would need, as they are pretty messy.  If you decide to keep one Oscar, here is a list of food that they like, and should have..

Good Quality Pellets, and sticks.
Good quality Flakes
Worms bought at your bait store, and cleaned.  To clean the worms, put them in oats for about one week.
Minnows bought at your bait store...the regular kind.
Crickets bought at your pet store.
(Always buy the worms, minnows, and crickets, this way you know for sure they have no pesticides in them)
Frozen veggies that you buy in the frozen section of your market.  Blanch the veggies first, let cool, and feed some to your Oscar...peas, green beans, carrots, and broccoli are good for him once a week.  I buy the mixed bag of frozen vegetables, and take out what I need when feeding my Oscar.
Frozen fish that come from rivers, and lakes, (never salt water fish) are also a very good source of food.  Buy frozen, and chop off a piece, let it unfreeze, and feed this to your Oscar.
Shrimps
Fruit now, and then...bananas, and mangoes...never citrus fruit.
Frozen bloodworms that they sell at the pet store, along with other food which is suitable for Oscars.
Never feed him feeder fish as they are mostly full of disease, and have no nutritional value.

I'm writing this down in case you decide to go with an Oscar.  This is how I feed my Oscar, and he is doing very well, and actually is one of my best friends.  
Think it over, make the right decision that suits your needs.  Remember that fish need lots of care, Oscars are no exception, and water changes must be made frequently.
I hope this helps.
