i got 1 damsel fish and a sand star
Off to something of a shakey start there IMO. Damels may look nice as juveniles, but many of them lose their looks with age and most of them become aggresive little buggers who will make life a real nightmare for any additions to the tank. VERY early to be adding a starfish, they extremely sensitive creatures and a 6 week old saltwater tank is still a pretty unstable environment. Personally I'd rehome them both.
I do not agree. Damselfishes can be excellent reef tank inhabitants; most of them will keep their colours and a few will grow prettier with age (Dominos, for instance). Also disliking a fish on the basis that it does not have absolutely dazzling colour is shallow in my opinion.
Unfortunately, they can be aggressive under certain conditions; however a Valentine's Puffer will not be harmed much, if at all, by any Damselfish.
Also, Sand Sifting Starfish are hardier than many other invertebrates, as are much of the other Starfish - it is only the
Linckia and
Fromia genera that are super-sensitive. However, just to be safe, a drip acclimation is still recommended (though by no means necessary).
Remember that Puffers are rumoured to nip the tube-feet of Starfish; monitor the Star for signs of damage after introducing the Puffer.
