This was my first purchase from Flip. My 7 year old son recently lost his last of two semi-aquatic crabe he had in a 10 gallon in his room. He was devistated. Rather than "replace" them, we elected to transform the tank to fully aquatic. He wanted something with comparable personality, and quickly latched on to the idea of crayfish. Obviously standard freshwater crays get too large for 10 gallon (especially if you want more than one).
Enter the Dwarf Mexican Cray. We found out about these online and couldn't locate any locally. Stumbled on Flip, who had the lowest price on these (with shipping). The night before they were supposed to ship we were browsing the site and say they also had Peacock Gudgeon's (sometimes mistakenly called Goby's). Emailed and asked if there was any chance of adding a pair to our order before shipment the next day. When I got to to work, first thing in the morning, I had an email confirming the possibility and an invoice in my email for the price difference (no change in shipping, either). All four (two Gudgeons, two Crays) showed up on Thursday as promissed.
Nearly two weeks in now, I can say they have survived just fine. The Crayfish are MUCH more personable and entertaining fixture in the tank than the crabs ever were. They are absolutely hilarious at times, and easy to locate, even with ample plants and hiding places. Customer service and communication from Flip was amazing, especially in accomodating our request to add the Gudgeons at the last minute. They are definitely on my shortlist now, amongst 2 or MAYBE 3 other online vendors I trust.
