Hello MFK,
It's been a while, but I need some help. Here are the facts:
I've got a 300 gallon rubbermaid stock tank pond (The 6' diameter one) in my basement laundry room with a shower curtain and clamps keeping it covered. The substrate is ~1" pool filter sand. The contents are one silver arowana ~18" give or take. Usually he eats hikari gold floating pellets from the surface, but he hasn't in a long time, I'm guessing going on a little over a month now.
Filtration is a FX5, 2 of the biggest hydro sponge filters and a power head sponge filter. Nitrates are about 10-30 PPM last couple times I have checked, I've done a 25% water change twice, and I've cleaned the FX5 by emptying it of the detritus filled water and shaking the sponges out in dirty pond water as not to remove too much beneficial bacteria.
I tried feeding him thawed market shrimp today, feeders the other day, and pellets on and off every couple days to get him to eat. Nothing has worked. There are no noticeable lesions or marks on the arowana, the gills look proper and he looks generally healthy.
Also, he used to be housed with some vieja, or paraneetroplus or whatever they're called now, in the pond (fenestratus, zonatum, regani etc.). Once the vieja reached sexual maturity though, the dominant female killed off quite a few of the other vieja, but never bothered the aro. That being said, I ended up getting rid of the last couple vieja since I couldn't keep the aggression down.
Is it possible that the arowana was stimulated to eat by the tank mates?
Is there anything else I can do to get him to eat? Get another larger more peaceful cichlid (like a snook or an oscar or something) to try and stimulate him to eat again?
Thanks in advance.
