Hi all! Newby here with a few questions. We recently bought a 75 gallon fresh water aquarium. We did all of the prerequisites as in treating the water, installing a heater and filter/aerator, etc. Started with 6 black skirted tetras and slowly added some other various tetras along with other various compatible fish. Today we added 5 Angel fish. Floated the bag for 30 minutes and let em loose. My questions are as follows. The Angel fish seem extremely lethargic and tend to group in one corner of the tank. Is this normal as newly introduced Angels? The next question is this. Since it was feeding time shortly after they arrived, I did my nightly feeding. The Angel showed no interest in eating. Normal? Lastly, I have read that Angels like to dine on frozen and live food occasionally. How do I ensure that the other fish don’t gobble up their treats?
