OMG! I wonder if they did that on purpose. If so, that's just mean, lol. Oh, btw, I'm pretty jealous that your Wal*Mart has dwarf puffers. I've been looking for a second one in my area for almost 5 months and no one has any.
The Wal Mart that I go to has a pretty well maintained fish dept and I let the manager know about the improvements and he said they got a new kid maintaining the tanks. :clap: They have dwarf puffers with no snails!!:goldfish::goldfish::goldfish:
