arowanas keep dying

[baracuda]

Hi i wanted to know if anyone can help me figure out why my silver arowanas keep dying. I have bought three so far and they all died. Its getting pretty expensive. The guy at the lfs told me they were pretty easy to take care of. Anyways, I had one in a 30 gallon tank and it did fine for a while but one day i came in and it was just swimming wildly all around in circles and upside down and also twisting. I want to know what might have been wrong with it and what caused it. Two of them died like this. The last one was my fault though, I mistakenly put the 6 inch arowana with my 12inch tiger shovelnose thinking it would be fine but the next morning i woke up and the arowana was gone. I looked everywhere but when i looked at the tiger shovelnose in the corner (with a smile on his face i swear) I knew what happened. His stomach was also swollen way more than usual.

i have never had a problems with silver, but are you sure all your water parameters are good? i know aros are sensitive to ammonia, did you do any large water changes or anything? how long has the tank been set up? i do know that juvy blacks are way more sensitive than the silvers.

if small aros get stressed sometimes they wont eat for a couple days then they will be to weak to eat and regain strength but deffinately check your water aros are real sensitive untill they hit about the 6" mark

my silver arowana died like the way you described, it is prob from an internal parasite or swim bladder infection. mine became sick after a 4 day power outage Are you doing enough water changes in the water? make sure you medicate your water to kill parasites. also live plants help keep my water cleaner

be warned aros are sensitive to meds i only use half the prescribed dose

How big are they when you buy one, cause I know that the one's under 6" tend to get sicker easier, try to get one between 9" to 12" they tend to do a lot better. You should also get some kind of flouting plant, fake or real the young aro's love the cover from it, if you use a real plant i'd use WATER SPRITE.

I agree with the plant idea. I have some fake plants that are real tall that end up drooping over and coving a portion of the surface (not too much), but they seem to appreciate it, especially babies.
