your best bet is to get another small tank for him and another ADF buddy. Goldfish, even fancies can get up to 8+ inches and a full grown ADF can still be swallowed.

ADF are very sensitive to water condition and the temp needs to be warmer than what a goldfish requires.

Also, as for your goldfish tank (I keep 7 ) - 40 gallons is ok for about 3-4 fancies. Yes you said you were getting small ones, but remember that these are babies and have a lot of growing to do! You shouldn't need a pleco and be very careful about adding one because they are just as messy as a goldfish and they REQUIRE driftwood to rasp on. Plecos that would work for your tank are bushynose/bristle nose and clown plecs. These stay under 5 inches and are some of the easier obtainable one. Do not get a "common pleco" - these grow 12-18" and will suck the slime coat off of your goldfish.


The frog should be fed the HBH Frog and tadpole bites or Reptomin sticks. But with a goldfish in the tank, the frog will not get its own chance to eat - frogs find food my smell, goldfish find it by sight and smell. I am sure you have seen your goldfish at feeding time - they are fast eaters. ADF are much more timid and slow and when housed with fish they often strarve.
