I have kept Dwarf Puffers for some time in a species tank. I did all the research and learned all that I could about them. I read all the claims of them being aggressive, etc. BUT I has also read several claims of success putting one into a large planted community tank. So I took my 2 DPs and put them in my 55 planted. All was ok for about a day. Yesterday morning I noticed one of the rainbows with a little notch n the tail fin. Last night I witnessed the larger of the DPs chase those poor rainbows all over the tank taking teeny tiny bites out of their tails. I quickly wrangled them up (how great that you can put your finger on the glass then net the puffer who comes to investigate! curiosity killed the cat) and put them into an empty small tank.
Point being when someone tells you that a Dwarf Puffer can take on a 3 inch fish and win they are telling the truth and it will eventually happen. In my case I believe only one of the pair was being aggressive, but thats all it really takes. My entire stock was hiding in the plants because of them. I found the whole thing very interesting, though I should never have attempted it as I did read all the warnings.
My fish are all fine. Luckily the DP mouths are minute and I stopped it very early on. Perhaps someone else will read this and some peaceful community fish will be spared the reign of terror a DP visit can cause.
