The pictures I have added here are on Picasa. The first photos were from when I set my tank up and the second photos were taken a few weeks ago.
I have a 90 gallon corner bow tank and have Peruvian angelfish (5), Neon tetras (12), serpae tetras (10), clown loach(1), and hatchets (2)
I run jungle vals on the sides and back, Kleiner sword in the center, along with bacopa, anacharis, dwarf hairgrass, duckweed, hornwort, bronze and red crypts, and val. spiralis.
The tank dimemsions are 30" wide x 30" tall x 54" long in the front with the bow. I run one metal halide 175 watt and two 55 watt power compact fluorescents. (lights are Hamilton in a retrofit as many lighting units were too large for my corner tank) This is just enough light. I would recommend a MH in the mix for a deep tank. I have a 10000K MH and two 6700K PC's. It is just right for me. In the daytime when it is bright the tank looks great with all the lights on (I run MH 8:30 AM to 5:30 PM and the PC's from 8:00 AM to 8:30 PM.) and at night when it is dark only the 6700K bulbs are on. I also have a 29 gallon with two 65 watt PC's with CO2 and those plants grow really red and beautiful whereas the 90 gallon gets just enough light to get moderate growth, so that extra 175 MH light just puts me into an acceptable range of light for my heavily planted tank. The deeper tank in my observation needs more light.
I love the driftwood and I have four large pieces in the tank. I glued some pieces together to get the driftwood to be 30" tall. (the angelfish love this!) I used epoxy and jammed two larger pieces together. I managed barely to slide these into the tank as the opening is small on the top of this acrylic tank. There is a picture of the driftwood on the Picasa web site.
I run CO2 and have no problems. PH 6.6, GH 4, KH, 3.5 I do 50% water changes weekly and fertilize at moderate levels.
My angels are no "angels" and are quite aggressive with one another. They are from wild stock. So far, they leave the neons alone and haven't eaten any of them, but rummynose tetras are perfectly shaped to "go down easy" and I don't think they would live very long in an angelfish tank.
I would be interested in the dimensions of your 150 gallon tank. You may need more than one MH bulb as two feet by two feet is said to be their lighting area, so a four foot tank would need two. I love my 30" deep tank. It can be a pain to plant and trim the hairgrass as it is so deep but the angelfish love it and it looks great.
Good luck with your angelfish tank! Keep us posted. Pictures would be nice.
