had an issue with some female guppys coming down with diseases and yes they helped send replacements for the dead and dying. but the males i got in retrurn wernt any better all 9 bunged into 1 bag 1 showed signs of fin rott and a day later so did another then 3 days later another has died a orange one. also id order 3 more khuli loaches to go with the 2 id already orderd then wen they arrived 1 was dead in the bag yes i get they refunded me for it but still. and they go on to talk about there packaging as if its something special it a box with amazon style paper wrap in it used to surround the fish then a small black bag and then 3 heat packs and a big heated gel pack thats it no poly box inside. when it arrived both times boxes were cold inside. these fish deaths are draining my enthusiasm for the fish keeping hobby.1st lot of boys and loachs are ok but its a lot of hit and miss id suggest you either visit them in person and select your fish or visit your local fish shop and get fish that way you can see what your buying and not getting a bunch of ill dying fish or dead ones.
