15 gal nano(pics of tiger shrimp&randall's goby added)

[mws]

My daughter is 11(you can see pink walls in her room.) and asked me if she can try saltwater. I know , at 11 is not looking promising(for her future husband's pocket) if she gets stack on a hobby.
Anyways this is what we came up with.
15 gal cube running on XP1 canister filter with Chemi-Pure Elite, LR rubble and tons of sponges. No skimmer, just weekly water changes. 20" Nova extreme pro(6T5HO).
Livestock she chose : 2 clowns(a must), azure damsel and Randall's goby with tiger shrimp(pair was made in 24 hours)
