Angelfish too large?

I have a single angelfish in my 46 gal bowfront with three bosemani rainbows and three bolivian rams.
Anyway, I've had him for about six months and he used to be very active and the first to the top to eat and would always act interested when we were near the tank, etc.
He has grown quite large- I would say 7 inches including the fins- and he is sort of listless, less active, and he often rests at an extreme tilted angle. The water is fine, so I'm wondering if it is possible that he is too large and no longer comfortable in the tank.
Any thoughts?
 
doubt he's doing that becuase he's uncomfortable. try a 25~30% WC and see how he reacts.
 
when you mean extreme tilted angle..are you referring to nose pointed up or down?

many of mine seem to sit about mid level looking upward.

if the angel is less active at feeding is it eating?

what are your water parameters? tank temp?
 
You said your water is fine but what does that mean? Is there any ammonia or nitrite in the water? The presence of either one of these can cause stress to fish. When was the last water change?
How much and how often?

Ammonia = 0
Nitrite = 0
Nitrate = 10 ppm

This has been an ongoing problem- a few months now- no improvement with water changes, which are about 33% every month.

I did just notice that my temperature is only 70- I have been battling a heater issue. Normally it is 76ish.

The angelfish is eating, just not as voraciously as he used to. Also when I said tilting I should have said he tilts to one side. His mouth is level, it's just that he leans to one side or the other- no preference on side.
 
Water changes should be at least 25% every week depending on the amount of food going into the tank and the fish load. Also 70 degrees is too cold for an angelfish. I would raise the temp. slowly like a degree or two a day until you have it at about 78 degrees. I would also increase the water changes and see if that makes a difference in the behavior and habits of the angelfish.

Ok thanks I will definitely try to up the WC- I am gone for weeks at a time but I have a roommate feed every day and he definitely doesn't overfeed, but maybe I can get him to do moer WC. I am also looking into getting a more reliable heater. Thanks!
 
Your parameters look ok but that temp. is way low. Most tropical fish fair better at 78/82 degrees (keep it steady) Angels are a bit more sensitive, so I would go to 80 (slowly) "T"
