hi this is my first time. im fifteen, i was wondering how big of a tank i would need to house all my fish
i have 3 oscar, 2 around 9-10 inches, the other around 5-6inches.an silver arowana around 19-20 inch.a jack dempsy around 6 inch, 2 plecos one 8inches the other 5inches, i also have 1 albino tinfoil barb around 3inch and a managuenses cichlid about an 2inch. almost 4 got i have a green terror around 3 inches icurrently have 3 tanks a 55g-2oscars,aro,big pleco,jack a 20g-smaller oscar, pleco,green terror and a 10g-managuense cichlid, and the tinfoil i was wondering if a 150 or a 250 gallon tank would be enough 4 them?

welcome to the site

I haven't actually works out exactly what you would need because it's very late here in the UK and I'm going to sleep very shortly. However, you have lots of fish and I'm afraid 250 gallons would not be the big enough to house them all. You're looking at well over 100 gallons just for the Arrowana. An absolute minimum of 55 gallons for each Oscar. Your manganese will require more than a single Oscar, you've got several other fish that get fairly big as well. If you cannot provide them with a large aquarium, I would think about reducing your stock dramatically.

i had read that its reccomended 300g per arowana... :-O


thats a load of fish you have, how do you find the time to keep all your tanks clean???

if you will keep the existing tank, a 250 gal for the aro and few medium size
tankmate will do. but if your idea is only one tank, then i would say
you need a swimming pool.....

WOW that's a load of fish sounds like a great combination hope you get a big enough tank it will have to be huge! with mega filtration.
Good luck with it, OFL will give you a good idea of the size tank you will need, i cant work that one out lol

im thinking a pond might do LOL. do you own a swimming pool??? its going to take ALOT of dechlorinator for that baby lol.

You are going to need a tank the size of a small room

thanks for the info, but just recently my managuense cichlid died so did my barb. i dont know why they died i just woke up and they were upside down i was real sad.All i have now r the 3 oscars , 2 dempsy , 2 plecos , a green terror and the arrowana. thanks alot agian. im going to start working over the summer to make some cash 4 a bigger tank

Test your water for ammonia, nitrite and nitrate so we can rule out poor water quality
