Hello, I am very new to the hobby. Just set up my first tank in my college dorm about a month ago and it’s going well. I recently decided to get a second tank (10 gallon tall) and was wondering if it was possible to put 1 angelfish and 5-6 cardinal tetras in it. I understand that generally angelfish need at least a 29 gallon tank but I am in a unique situation. Since I am moving out in 10 weeks I was thinking that if I got a small angelfish from petsmart he wouldn’t grow large enough to be uncomfortable. Then at the end of the 10 weeks I would be giving my fish back to petco. If this doesn’t work please let me know.
