The trouble is that those that survive in these small tanks are the exception rather than the rule and are often kept by experienced hobbyists or those willing to go the extra mile (and understanding what that entails in advance with regards to dragonets). Generally IMO larger tanks should be recommend for 95% of hobbyists out there.
Yes, I did say it was a challenge for a beginner and they need a specific tank. Although honestly, it mostly takes dedication. They can be time consuming and can live... what? 15 years?
Taking vacations becomes more of a problem too since you really shouldn't trust family/neighbors to take care of a mandarin in a nano. I paid a fish sitter when I had them. Then again, I had 6.
