For ACF it is a very easy set up -
* 10 gallons for one frog
* no gravel substrate - smooth rocks that can't be eaten or sand
* live or silk plants, not plastic because it will tear the webbing between their toes. For a very easy live plant, I recommend live Water Wisteria - it is currently in every single one of my tanks including my froglet tank. I leave it floating and it grows like crazy. It makes a perfect buffer against lighting to keep the frog from getting stressed, and the frogs seem to enjoy resting in it at the water's surface when they go up to breathe.
* hiding places are a must - these frogs do not like overly bright lights (they have no eye lids) and a frog that knows it has a safe place to retreat to feels braver exploring its tank
* 78* F is good for a juvenile (under a year) due to their faster metabolism for growing. an adult should be kept around 73*F.
* because you are a new owner, do not keep with any type of fish (besides a 30 gallon with multiple goldfish would be overstocked)
* diet - - nothing freeze dried, no fish flakes, and do not feed "feeder fish" (feeder fish are kept in very poor conditions and are most often diseased - it is not worth risking your frogs' health for a cheap and un-nutritional snack). Best diet is HBH frog and tadpole bites for young frogs/ Reptomin sticks for adults. Treat with bait-store purchased earthworms (do not use worms from your garden because there is no way of knowing what fertilizers or pesticides they could have come in contact with), frozen bloodworms are also a favorite treat. Do not feed beef heart - it is exceptionally fatty.
* KEEP THE LID ON! these frogs are escape artists and can get out of even small openings - a mesh screen top (what would use for a reptile tank) is best.
* internal filter - an Elite stingray rated up to 15 gallons is a perfect size for the 10 gallon tank, and you can adjust the output to direct it at a back corner to minimize water disturbance.
* lighting - minimal. The need a day/night cycle - make sure the tank is in a room that becomes dark at night. With out eye lids, a constantly bright room can be stressful to them.
