Tank to grow massive silver arrowanas

  • We are currently upgrading MFK. thanks! -neo
an aro that small WOULD have trouble finding food in a 500g and you would find yourself constanty taking out uneaten/wasted food. they are pretty fragile fish and only a very very small percentage of wild baby aros make it. start him in a smaller tank if you want him to live and readily accept food.
 
I want about 3 silvers, more than that will crowd the tank if they grow large. This will be my first time owning an arrowana so I want to make sure I do it right. I will be posting soon about water flow in the tank and get some feed back on that. I don't have a pond, but I am in the planning stages of setting my 500 gallon up. So 3 little silvers in 500 gallons will be great for them lol! Do arrowanas usually come to the surface when feeding? Or rather do they know when it is feeding time when they see you open the lid? Small freshwater fish swim around mindlessly and if they see food they eat it, otherwise it falls to the bottom. Oscars however immidiately respond to feedings. How are arrowanas when feeding?
 
My aro comes right to the top right when the food goes in since the day I had him so i wouldn't worry about them getting to the food
 
they cruse the top then get any food they see or hit with there barbbels. i currently have 6x 3-4" silvers in a 120gal(4'x2'x2') they never have any problems with finding food. they will learn were you put the food in and respond to you by going to the food. i personally would put them in a 20gal to start. then after they are in the 5"+ you could move them into a larger tank like a 180gal or something. i wouldn't put them in the 500gal till they were in the 12-16" range. i would only have them in a 55gal till they were 8" max. this is my professtional opinon and my way of rasing silver aros. i have had/raised many from eggsacks to 24"+. my personal best was 3" to 24"+ in 10 months. that fish started in a 20gal till it was 4-5" then into a 180gal. gl with the community as i am an example of an aro community struggle. after some 20-30 aros i have these 6 that are going good so far, just threats with little to no niping. you must be ready to seperate them if there is an issue as they will get around every divider you come up with. nothing is worse then waking up to dead aros.
 
Definitely get the 3-4 inch ones as they will be much more stable then the smaller ones. As far as the tank goes it's up to you. I wouldn't put them into anything smaller than a 55. You can put them in the 500 with no problem assuming the tank is cycled and water parameters are correct. Also at that size make sure nothing is going to eat them and make sure they don't have to compete for food. Just make sure they're eating good and gaining weight! Good luck and post some pics!

Intersting, so is it better to just keep a single arrow?

when real small yes. as they get bigger they can withstand more and can survive the establishment of a higher achy. when they are to small they will get their tail injured witch ultimently leads to their death. you could raise them alone till they are larger(5"+) then try to mix. i have found that if you are going to mix them it must be at this size range or it stands a really strong chance of not working out. even so it is tough to get a pair or group. most of the time the rule of thumb is 1 or more then 3. it can work as a pair, but from my exp it hasn't. yet at the same time i have had 10 together and it went bad. could have been cause i started then together with eggsacks. i also could have just had a mean one or 2 that just wouldn't work ever and they just eliminated the commpition. i ended up moving some, some died, sold some, some got eatten in my attempt to keep them seperate. in the ed i have had to sell most of the aros cause they didn't mix. alot of people just grab a few aros and don't have any issues, but with me that has not been the case.
 
I just read it, thank you. Looks like I will start them in a divided 55 gallon. I'm gunna fed them a big variety of food cuz I want them to grow fast and large. Other than obvious size differences, what tank mates are good with arrows? I want to stick with an amazon theme. I'm wanting a tigrinus cat, a variety of knife fish or long finned oscars. Will oscars be to aggressive for adult arrows?
 
I would never put another Arowana with a oscar my first aro was with my tiger long fin Oscar for a week then just decided to rip it's throat out and It died instantly not saying you can't but after that I wouldn't trust it
