From experience and the other reviews I’m just reading these seem to be a hit or a miss. I ordered 8, two were dead on arrival, one was lethargic and didn’t make it past acclimation and then I lost a fourth in the tank. Please note that they did refund me for the first three I told them about and I just wrote off the fourth thinking I was going to lose them all eventually. Four of them are still with me and healthy. I wanted more so they would feel comfortable enough to enjoy then tank so I ordered 8 more. All 8 of these arrived healthy. All made it through acclimation and are enjoying pretreatment in their iso tank for a couple of weeks. 12 out of 16 or 1 pretty bad set and one excellent set. Either way AquaHuna stood behind their product.
The order came arrived when expected per their delivery instructions. All 8 emerald dwarf danio arrived alive, active and healthy. They survived acclimation and surprisingly they were chasing behind my larger zebra danio immediately. Their action is great in my fast moving 29 gallon. I’m waiting to see if they color up like in the main picture before I add any more.
Ordered these to put into a 100 gallon tank with fancy goldfish. I read they are compatible. It has added extra movement in my tank. They are peaceful and haven’t bothered the goldfish. My goldfish leave them alone as well. All arrived active and healthy. Mine are eating blackworms, repashy, vegetable, sinking pellets same as the goldfish. My tank is planted so they have some hiding places if needed.
