Two weeks ago, I bought a High Back Gold arowana around 11~12" and added her into my tank which has a flowerhorn.. Surprisingly, both fish got along well without even a slight scuffle..
The arowana was eating well until two days ago when I saw that my flowerhorn was sick again so I moved him to the hospital tank.. I changed around 80% water hoping that would prevent any further outbreak of whatever that infected him (the fh had pop eyes prior to this but recovered and now the disease came back)
My usual water change routine is 50% weekly with 1 tablespoon of aquarium salt for every five gallons of water changed..
When the water was drained to almost 80%, the aro started rubbing against the glass and she continued to do that until I filled the tank with water..
After an hour or so, I tried feeding the aro superworms and she ate.. Then later that night, when I put in the worms, the aro just let them sink to the bottom(they were still there the next morning).. Yesterday, the same thing happened..
The aro is also occasionally rubbing against the glass and swims at the bottom more frequently than before (during the first two weeks, the aro just swam around the surface and rarely swam to the bottom.. at most, she would dive down to grab any worms that were sinking)
I really don't know what is going on.. I don't have a test kit so without knowing the water parameters, can anyone tell me what could be wrong?
I've a theory that maybe I added too much salt at once? But I'm just replacing the salted water that I siphoned out with new salt..
