Pros & cons on buying juvenile pr adult jardini arowana?

  • We are currently upgrading MFK. thanks! -neo
Looks like a good buy nice healthy jardini you've got yourself there.
There are pro's and cons for buying private or lfs
Buying private usually means the fish is already feeding and in healthy conditions , it also means any nasty diseases /deformities it could have from the wild or born with have already become apparent that this stage.
Private sellers give fairer prices too if there realistic about the value of the fish.
Shop bought jars are generally juvenile and small which is great if you want to grow one out to get it tame to yourself, but like I've said above that comes with problems.
Some shops will give you a guarantee with fish as long as your water p's are in check and it's of no fault of your own , where as private bought you'd be lucky.
Anyway it seems you made a good choice looking forward to updates on its progression.
Welcome to the jarmy army ;) lol
The only thing about this one is it won't eat market shrimp.. I tried but he won't take it.. The previous owner only fed him bloodworms.. Is it going to be hard to train it since it only ate bloodworms for 3yrs?
 
Start to season various foods with defrosted bloodworm that'll at least keep the taste familiar, it's done well to get to this stage on just bloodworm.
It'll be a challenge but you'll manage it eventually just don't give up , it's big enough to starve onto different foods so you could try that route
 
What do you have that might interest me?

I have a Leichardti Arowana that I was thinking of selling. Decent pick on the Jardini tho. Might be stunted for a 3yr old feeding on worms, but it looks healthy. And don't pay too much attention to the peeps on your other thread. Their size predictions for your other fish are wayyyy overblown unless you're planning on putting your fish in a large pond and growing them out. Aquarium raised RTC rarely get over 2.5 feet long, clown knives maybe 2ft max, pacus 18in, and the Jardini will also max out at 2ft. And BTW, you have a 180 gallon aquarium (6×2×2) not a 130 gallon. Those "pros" on your other thread never picked up on that but were adamant on telling you that your fish are gonna get too big for your "small 130 gallon" tank. All of your fish will do fine for a long time in your 180 gallon.

Thanks for letting me know. That's what i thought also is there a cure for stunted fish?

I'm sorry it's 135 gallon the dimensions were wrong. The correct dimensions are 6x2x1.5

Even with a 6x1.5x2 135 gallon, your fish will do well for a very long time. As far as stunted growth is concerned, just good feedings with good food is the key. If the aro is picky and only wants to eat bloodworms, try starving it for 5-7 days and then try feeding it market shrimp or tilapia cut up into small slivers. Make sure, after you slice up the shrimp or tilapia, to rinse them throughly in cold water so that it doesn't cloud up your tank. My preference is tilapia because shrimp will start to get expensive once your Jardini gets bigger and starts to eat like a real monster fish.

Okay thanks good to know. But i have a problem with the jardini right now. Every morning he is swimming slanted I did a water change right away and it kinda helps, but couple hours later he's back at being slanted again. Then i removed the 2 silver dollars and 2 pacus as he keeps on chasing and biting them i thought this was the cause of him swimming weird. Still the same. It's been likes this for 2 days already. Also I noticed that when i turn off the lights it made it worse but as i turn on the lights he swims straight again. Water parameters are okay except for nitrate which is around 10ppm.
His tankmates right now are baby RTC, knifefish and a bichir which is the same size as the jardini.
Do you have any idea what's going on? I am really worried about him..
 
Your fish probably has a minor case of swim bladder bloat/disorder. If it's been eating freeze dried or frozen bloodworms for awhile, that's probably the culprit. During the processing of freeze dried or frozen bloodworms, air bubbles are trapped inside the worm's cavity. Consuming enough of the worms can lead to an accumulation of air in the intestines causing bloating which leads to abnormal floating problems. The fix for this would be to wean your Jar off of bloodworms and to let the accumulated air slowly dissipate.

Another cause for swim bladder bloat is an intestine infected with parasites. If your fish is truly infected with intestinal parasites, you'll see stringy white poop trailing from the anus. Some signs of a parasitic infection of the intestines is stunted growth from malabsorption and abnormal floating problems. Just like when you have an upset stomach or food poisoning, your stomach gets bloated with gas. A fish with a parasitic infection will have intestinal bloating causing abnormal floating problems. If your Jardini has intestinal parasites, it can be treated with metronidazole.

You should probably approach this problem conservatively by first weaning your Jardini off of bloodworms. In addition to that, you can raise the temp of the tank close to 82 degrees to increase it's metabolism so that it can absorb some of the extra air in it's intestine (plus the higher temp will help kill off some parasites). Also, you can add aquarium salt, one teaspoon for every ten gallons, to the tank to aid in the Jar's intestinal motility so that it can expel some of the extra gas in it's intestines (works just like a saline enema). Try these things for two weeks and the abnormal floating problems should get better. If they don't get better or they get worse, you should look into treating for intestinal parasites. I hope this helps.

Heres a video of him when i was doing water change and cleaning substrate.

Today is the 4th day since i got him and he only ate 1 cube of bloodworm the first day he got into my tank. For the white stringy poop, I don't see it trailing from him.

every time i tried to feed him he avoids me like he is scared. Tried market shrimp and food sticks but still won't eat. I'm worried because it's been 4 days since he hasn't eaten yet,

Do you think slanted like 90° when light is off alarming? But when i turn on the light he'll be startled for a bit and starts swimming straight.
 
Please try to pay attention to his pectoral fin one is kinda crooked. Or is it just me being paranoid?
