In the past 2 weeks I've lost...2 snails, 1 brittle star (which I didn't know I had) and a small white tiny crab (another surprise guest).
My water parameters are fine and my other occupants are fine (sailfin tang, tomato clown, scooter blenny, yellow blenny, red hermit crab and rock anenome)--but I did a 20% water change, plus flushed the filter media and siphoned the sand for leftover food.
The crab and snails were new to the tank (about a month)-- which I purchased to replace the snails I lost when my temp spiked 3 months ago. I did the usual hang the bag, add water, etc. but have no idea why they died. Any suggestions? They didn't appear to be "harrassed/banged up" just died.
I'm thinking of trading my sailfin in...it's become a total tank hog--or maybe the others are just normally wimpy. I thought I read up enough and that it is a "community-type" fish, but maybe I read wrong? Is it fairly normal for a tomato (who was very territorial prior to the sailfin being added) to find a piece of lr for a "host" rather than an anenome? It only comes out once in a while, but is fine at feeding time. All seem to be getting enough food--I feed a variety (not all at once!)--
frozen brine shrimp, frozen nori cubes, frozen shrimp cubes, nori sheets (clip to tank for tang-grazing),
Prime Reef flakes, Spiru Flakes, my own mixture of Selcon, fresh shrimp & scallops and about once a week live brine shrimp--so I think there's enough variety, maybe too much?
Anyway, thanks for listening--everyone have a safe, healthy and happy holiday season.
