So pretty, but incredibly fragile. I bought 3 a month ago and 3 more 2 weeks ago. Despite slow acclimation, an established tank, lots of plants, clean water, plenty of food (blanched zucchini and spinach, algae wafers, algae flakes),... seemingly ideal conditions that my regular otos thrive in,... I've lost 4 of the zebras now. One from the first batch died after a week. Two from the 2nd batch died the first night. And the last one from the 2nd batch died just 15 minutes ago. I don't know what to do. I'm going to research them some more and test my water again. They really are beautiful and I would love to keep more... but they're not cheap and I don't want to risk having more die on me.
