So I am up for a challenge and would like to create a nano tank using all parts I have laying around the house (therefore the challenge cause its going to take some thought and macgyvering). The only tank I have is a 10g I used for a quarantine a couple of times. My wife says I should use that, and I got all excited until I brought the tank upstairs and realized how tiny it was. What would you guys think would make a better zoa nano a 10 gallon or say a 20g long thats only 20 bucks right now at petco? IF you say the 20g please insert a comment/trick you have used to get your loving other to agree. I've tried, you can have a clownfish and there will be more room for even more coral, but both fell flat on there face.
