Sick Arowana, Can't Figure Out What He Has

Personally I don't think it's a Ph shock or PH related illness, 70 minutes is fine for moving .9 on the PH.

It's more likely an internal infection of somesort like already mentioned in which case I would recomend Esha 2000 to treat it with.

personally i thought 70 minutes was good as well. and since he was great at first i was thinking ph shock didn't have anything to do with it. but since i'm stumped and these guys agreed it wasn't long enough i am now having doubts. recently i bought a freshwater barracuda from the same place, they said they had nuetral ph, so i did 30 minute acclimation, he seemed like he had ph shock cause he didn't seem right from the start, never ate. thats why this time i made them test it in front of me and sure enough 6.3.

Just to check but i take it ur scooping tank water into the bag every 5mins or so to adjust the PH right?

PH shock isn't an issue, I accdiently climatised a couple of rays from 6.5 up to 7.7 in under an hour, I set the drip a touch too fast! But within 10 mins they were actively feeding.

correct. every 10 minutes i would take 2 cups.

since arowana's tend to prefer slightly acidic, and blacks are more sensitive to begin with. you think that maybe just the ph itself is too high for him and he is gettin alkalosis? i had a silver in there since i started that tank but they are more hardy, he came from a 7.0 store. so maybe the jump in ph AND the ph is just too high for him anyways. what do you guys think?

just found this


The Black Arowana fish (Osteoglossum ferreirai) comes from South America in the Rio Negro basin. They grow up to around 40 inches / 100 com, though they seldom reach this length in captivity. The Black Arowana fish eat live fish, large insects, spiders, Tubifex worms, and may also eat pellets and flakes (not all specimens accept pellets and flakes). Young Arowana fish of this species tend to be delicate, though older fish tend to be more hardy. They prefer a pH level of 5-7 with 6.4 being the optimum level, and temperatures between 75 and 86 degrees Fahrenheit (24-30 C).
