    Hi all,

    First of all, this is a great forum, I've been reading and learning a lot from other members.
    I've been keeping a 2' nano reef tank for almost half a year now, and everything's been going very well.
    I'm setting up a 2nd marine tank, but fish only, without live rock or coral.

    Here's what the setup's like:
    - standard 2' tank (bare bottom, without substrate)
    - 2 power heads (with sponges)
    - heater
    - LO T5 lighting

    Stock:
    - 1 damsel (moved from reef cause getting big and territorial)
    - will probably get 1 or 2 more similar fish

    So what are the pros and cons with this kind of setup?
    Will I get away just fine with this very simple setup?

    Thanks in advance,
    Steven

    No live rock means deminished filtration. What you going to use for filtration ?

    Also it means more stressed fish as they need a place to retreat to when they feel threatened or stressed as well as to sleep. Brent is also right with the diminished filtration from live rock

    so the sponges attached to the power heads are not enough for the biological filtration?
    So fish only tank is not a really good idea then?

    Fish only tanks are cool but you need live rock for the bio filter and the above reason I mentioned above. The sponges wont be enough to maintain your tank especially when you start stocking the tank up with fish

    Remember not all fish are an active swimmer, most of them are feel secured hiding the rock. Live rocks not just for bio filtration its also serve as a shelter.:thumbup:

    Adding another damsel will be his death sentence.

    This one already claimed the tank. It will kill the newcomer. As it is only a nano, and no LR to create separate areas or territories, please do not add another damsel.

    I agree with RiaanP when I first set up my 40gal we got 3 damsels why? Because we didn't know any better and neither did the people at the store. But, it turned out badly. After we added two clowns the damsels got very aggressive one more than the other eventually they killed one of them which caused concern I then noticed that the less aggressive of the two remaining was missing some of his fins and looked like he'd been chewed on. Eventually I had to spend several hours removing most of the live rock I had set up in the tank and hovering over the tank with a net to catch the aggressive damsel so we could trade him in:(. My advice no more than one damsel especially in a small tank!

    I would recommend adding a little sump with a TS1 skimmer in one compartment, and the return pump with some smaller liver rocks in the return chamber. Barebottom is a matter of preference but you do get alot of benefits from substrate. You should take the sponges off the power heads as these will be nitrate factories. Add a few KG's of live rock and sell the damsel then you can get some fish in there. Rather steer clear from damsels as they are too aggressive
