20l build

So a few months ago I started a 20L nano tank. I wasnt sure which direction i wanted the tank to go and to this day I'm still not sure. Im leaning towards blue stripe pipefish but havent decided yet. As of now it has a pajama cardinal<-my daughters favorite fish, a yellow clown goby, and some snails.



Its got a 10g sump, a jebao wp10 a nano koralia, and a 4 bulb t5 fixture.
