I moved my pair of pacus to a makeshift tank until I can build my monster tank for them; they were sharing a 75 with 2 oscars and it was way crowded. All my boys (girls?) are juveniles, no one over 4-5 inches; nonetheless it was a heavy load for my wet/dry and ac 110. My makeshift tank is a converted cast iron tub (don't laugh), which I have used to house my o's before I got the 75 gallon. They have been in the tub for over a week now and are still very skittish, plus I don't think they are eating. They were excellent eaters before and very calm, so I am a bit worried. Their new home is definitely adequate for the time being; approximately 70 gallons, temp around 75 degrees, water quality is superb. I am hoping they will adjust soon. If there are any good suggestions, I would definitely welcome them. Thanks, Tom
