28 Gal fresh water Aquarium

Question
Hi,   I have a 30 gal aquarium and I kept two ramirazi 1.5", two tinfoil barb", four Redeye Tetra 1", four Red Zebra Dinos, two angel 1.5" and 6 guppies about 1.5". The all guppies died with in two days and their fins were nipped badly. Rest of the Tank mates seems to be doing just fine. But I really curious to know who would have done it. I love guppies and I got the most beautiful of all but really dishearted to see them dead. Please help....

Answer
Hi,
The Danios, Barbs, and possibly the Tetras will have nipped them because of their irrisistable long fins. Therefore, you shouldn't buy any more guppies, as the same will probably happen to them, and you can't stop them.
They are lovely fish, but need harder water than the others and will be nipped.
Best wishes,
