Question for stocking 150 gallon tank

[Lady10Godiva]

I do have angelfish in a tank with clown loaches and they get along fine. I also have a larger tetra, serpae tetras. The clown loach school is 10 fish (they are in there to grow out for one more year, our oldest ones we have had for a year and a half and they have just reached 4"). The tank they are in is a 6 foot 125 gallon tank, but it is a short term tank, not their forever home.

One thing to consider about balas is that they are really fast swimmers and might make other fish feel scared and hide a lot.

Ok Peeps, here it is. My lfs buddy, is not just my lfs, but an actual friend, so I trust him. I had him test my water yesterday, because I bought a young and small Angelfish from another store earlier yesterday, and after floating the bag for a half hour and releasing him into the tank, he died within an hour. The store that I bought the angel from did not have the tester kit in stock, and I was looking to buy the three bala sharks from my buddy's store later that day.
Here are my test results:
ph - 8.0-8.2
G.H - 180
K.H - 200-220
Nitrate - 10-20ppm
Nitrite - 0
Ammonia - small trace - due to dead fish and left over food. But not enough to worry.

I got my three bala sharks, they are about 3-4" long and they are doing well. I figure in a week or two, I will test my water again, and get the next fish.

Just a suggestion - many of us have purchased the API freshwater liquid test kit from Amazon - it's less than $20 - just so you can do it at your own convenience.
