Tropical or Marine Fish?

[! a u r a]

I have just purchased a biOrb 30 for my bedroom. It is all set up for tropical fish with light, heater..etc. However, I am wondering whether I should scrap buying tropical, buy a marine conversion set - and a small group of marine fish. All I want is a small clown fish, a star fish, and a sea horse. Do you think this is possible? If not, discuss with me what fish I COULD get or what you think I should do? It's just with me being so new to looking after fish - I don't really know what to opt for. ALSO - Do not go on at me about having a 30ltr tank - I wanted a biOrb and I know people who successfully keep fish in them - that is that.

first and foremost

never ever put marine in a bio Orb it isnt right for them. they need larger and a more original space to swim in. eg. a normal rectangular tank or bowed front glass and it has to atleast be a 30 gall tank. bio orbs are not the best.

i would say stick with the tropical even tho i dont like bio Orbs personaly but for marine they are just not built for it

thanks hoped this helped
