Hey there, i was actually thinking about starting up a dwarf puffer colony, and was wondering if a 20 gallon tank would be sufficient to hold them? if so how many.... and what type of environment do they prefer? thanks
in a 20 gallon petsmart will tell you around 20 but for good advice try 5-6 try not to get two males unless they have a very dense plant set up with alot of places to block the line of sight and plenty of females
