We have them in several different set ups. I will take some pictures soon to show you. Our two largest amphiuma's (which we feed F/T adult mice & night crawlers) are in our largest and most impressive tank. It's 180 gallons. We have hiding places in rocks and drift wood for them and they have fake water plants, live fish and 2 canister filters. We also have 2 pond set ups each with 2 or 3 inside. Then we have a smaller one in a 10 gallon, a smaller one in a 20 gallon, one that we personally harvested in a 55 gallon, 1 that lives with our lesser siren in a bow front 20 gallon and our smallest baby in a 10 gallon and it lives with two orange bellied newts and 2 wild caught unidentified salamanders.
We feed them mice, pinkies, hoppers, and worms. They will come right out of the water to eat.
We've already witnessed lots of interesting behaviors about them. We only have 2 that seem somewhat aggressive and we haven't been bitten as of yet. An amphiuma yawn is quite impressive. They also shed their skin, but we've never witnessed them eat it. Lots of materials tag their legs as "useless" however in the water they seem to use those tiny legs often.
Sex is hard to determine. The coloration of the cloaca doesn't seem to ring true to us, unless we have all of the same sex, which to have all of the same sex out of 12 seems kinda hard to believe.
We don't have the proper set ups yet to breed, however that is our main goal for the future.
After having these animals for quite some time now, we feel that they will have a good chance of moving up in the pet trade with the right advertising. They are super easy to maintain... they are very different from your standard pet and they are super cool and interesting to watch.
We test our water routinely and Lane can always be found messing with cleaning filters or vacuuming up waste with his python (Which proves quite handy with any aquatic set up).
We would love to hear some personal experiences with others who have them.
