Reef tanks are expensive and not for a beginner- although starting with a LR
fish out cycle process, and building slowly through the process of cycling with a shrimp in and building a clean up crew (most of which can be find as hitchhikers in live rock), you will have plenty of time to think about whether or not you want to take that next step. My puffy fowlr
is starting to transform into a reef tank slowly, which inspired me to start a nano tank in my room (10g, just gonna have some different types of coral and a clean up crew). It can be super expensive if you want all the bells and whistles- but with time and determination it can also be relatively cheap.
