So my parents wanted a fish tank to liven up an empty corner of the living room. Long story short, they got one and I'm left taking care of the fish...not too bad at first and I've actually become really interested in the hobby since. A few days ago we had a small arowana and 2 red parrot fish. The aerowana for it's size had some room to swim (wide 60 gallon take), and the parrot fish had established hiding spots among the decorations. I came home yesterday and there are now two angel fish and 2 discus.
Now the angel fish and discus have no forestry or drift wood to hide in, which I could get, but it takes from the arowana's swimming room, the temps and pH levels are different for all the fish, some of are close enough IMO
, but the discus totally throw it off as they need higher than normal tropical fish temps. Also one of the parrot fish has begun to develop black spots on it's fins, which I assume are stress spots due to the new fish, and they are bullying and pushing the discus away when they get near their little caves that the parrot fish hide in. I need to figure out what to do with these fish to keep them all happy and alive, which at this point, I don't know if that's even possible. At the moment I have the temp at 82, ph levels are around 7.6 but constant. I do have some aquarium salt in there just for good measure since it's a fairly new tank, and ammonium is at .5 PPM
. So I was hoping I could get advice on a happy medium for all the fish, or to just start separating and selling the fish to start all over, which I doubt is possible...not my money. And any ideas on how to drop that ammonium level to 0?
