Fish Food? or Tankmates?

[jclyde13]

Why would you need opinions from experienced dat keepers to decide if your aros will eat your dats? Sounds more like a question for experienced aro keepers to me...

I have had my aro for a year with much smaller fish than your dats, and I have not lost a single fish since I set up the tank a year ago, so just based off of my experience alone, I'd say you should be fine, but it probably depends on the aro. btw, my aro is now around 2' long, and my smallest fish are a 7" senegal bichir that is about the diameter of a man's middle finger (which often comes to the top for air and has never had any kind of interaction with the aro), and two 8" lima shovelnose cats.

its nice to have a biotope tank w/ mixed fish of many sizes. all i can tell you is that trial and error is the key; as all fish personalities are different, like humans.i have a 4 foot by 3x3 foot show tank and my 20 inch dovii is the king. but he lives with all type cats even corys, angels, mesonautus festivus, and red hook myleus r. and simply enjoys his pellets.iv'e seen his aggression but not in this tank. he's been there 7 mos.i guess there are no challenges and no conspecifics.i dont know of what i should attribute this peace; i just enjoy it.

yeah I think its a case by case thing...my 12 inch odoe pike KILLS feeder goldfish but wont touch any of my small clown loaches and other small fish. I do think that it shouldnt matter that your indo is the "Boss of the tanK" because if that aro wanted to it could take care of them no problem

I've seen that size combo work for years in some friends tank. The spines on the tigerfish do look like an apetising meal.
The arros look like their fed well and the tigers look healthy also.
Iwiied- how long you had the combo for ? The tigers look somewhere between 5-7 inch.

I keep small syno petricola catfish with 12-14 inch ITs. The syno started at about 2 inch, now they are all 4-5 inch. The synos have so many spines and fins the tigers just don't bother.

they'er out the tank and back to their growout tanks guys, thanks for the advice. the problem wasn't so much with the arowanas, although i dunno about the jardini when he stop getting chased by the NGT. the problem was the NGT keeps chasing the small dats.

i've just put them in yesterday and keep an eye out for any agression, i'm about 90% sure that they will be ok with the silvers, as they're very peaceful and have never even been on live food, i gave them feeders once and they couldn't even catch those. the NGT is about 10-12 inch, the smaller dats are about 5 inch.
same with the rays , they have never been on live food and actually was kept in the grow out tank with the tigers when they were even smaller, they don't know how to hunt.
the problem is with the NGT it's always been chasing the Jardini around very aggressively. and after putting the small dats in , it starts going after them too. the jardini is big enough to not get killed by it. but i 'm not sure about the small dats so they went back to their growout tank

mm.. my guess would be the the jardini chasing the smaller dats unless you have someone else bossing the tank.. maybe not for food but for pleasure/hierarchy.. this will probably cause the dats to stress out, possibly hunger strike.. and even worse.. if one of the dats are the boss you might have some pretty damn hostile dats later on.. I've never had any problems with silvers and small fish, they tend to be pretty docile.. (not that I need to tell you that if you raised yours to that size)

Only problem I can see from the silvers are during night if they "auto-taste" one of the dats.. the spine will probably deter the aro from further inqueries of how to or not to eat dats but the dat might be hurt.. grow them out some more and add them when they have a reasonable chance of leaving a fight with the jar standing..

just my 2 cents..

 

[ettfettbranamn]

nevermind.. note to self, read the entire thread before "wasting" letters..

yeah that's basically what i'm gonna do. grow them out more before putting them back in. just getting a bit impatient with their growth rate and keeping more than 1 tanks.

yeah, I know what you mean.. they seem to stay quarter-sized forever.. when they reach the size of a palm they are almost indestructible in terms of dealing with other fish though..
