Thanks. Tank has approximately 75 gal of water in it with a generous
freeboard around top in case anyone jumps. Photos not possible now because
tank is fiberglass, but I may try moving one into a clear tank. So far they
have behaved themselves pretty well but we have only had them since
yesterday. I was impressed that they survived being trawled and kept in an
unaerated live well at 30 o C all day. Three of 24 died on drive back from
river - 6 died last night. Specimens reamining look good, but so far have
refused food.

Jan,
The only published account of their aquarium care Išve come across says
hiodontids need large aquaria (over 100 gallons), can be conditioned to take
prepared foods, grow quickly, and are highly suitable specimens for outdoor
ponds. Since hiodontids are surface feeders that frequently leap from the
water while catching insects, the need for tight-fitting cover goes
withoutsaying.
If one can infer aquarium behavior from behaviors in the wild, it may be
best not to overcrowd goldeye. According to one report, goldeye like to keep
a space around themselves, and nip and chase away other goldeye that get too
close. Their population density in one Canadian delta was estimated at one
fish per 50 sq m (538 sq ft).
Please keep as apprised of how your goldeye are doing, since captive care
requirements are virtually unknown. (Get some photos, too!)
