Jmvanness Posted January 31, 2015 Share Posted January 31, 2015 Last night I had 4 healthy happy chromis. This morning, 0. No bodies. Not in the sump or overflow. Any ideas? Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted January 31, 2015 Share Posted January 31, 2015 Maybe just hiding real well? I recently got a large green wrasse who went into hiding for 5 days when introduced. And he was used to being in a tank. Quote Link to comment Share on other sites More sharing options...
Jimbo662 Posted January 31, 2015 Share Posted January 31, 2015 Mine would occasionally go into hiding to for no reason. 95% of the time they were out chasing each other around and 5% completely gone. Quote Link to comment Share on other sites More sharing options...
Jmvanness Posted January 31, 2015 Author Share Posted January 31, 2015 Oh, maybe that's what is going on. Everyone else is out and about. Maybe they'll reappear. Quote Link to comment Share on other sites More sharing options...
Timfish Posted February 1, 2015 Share Posted February 1, 2015 trans-dimensional portal behind the rocks. Some fish are pretty good at annoying their owners that way. As mentioned above it's almost certainly behavior, the odds of a unknown predator or pathogen taking out 4 fish chromis overnight is pretty slim. 1 Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted February 1, 2015 Share Posted February 1, 2015 So I'm assuming the chromis use the blue portal... does that mean you have anthias that use the orange portal? <--- Sorry, slightly obscure reference! [emoji57] Quote Link to comment Share on other sites More sharing options...
Jmvanness Posted February 1, 2015 Author Share Posted February 1, 2015 I get it Ty. I have the second one, you're welcome to come play anytime. 1 Quote Link to comment Share on other sites More sharing options...
Jmvanness Posted February 1, 2015 Author Share Posted February 1, 2015 That's what i was thinking Timfish, 1 or 2 maybe, but all 4? They still haven't reappeared. Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted February 1, 2015 Share Posted February 1, 2015 Mine are masters at hiding in my SPS colonies. I don't even see them until they want to show themselves. Quote Link to comment Share on other sites More sharing options...
Jmvanness Posted February 2, 2015 Author Share Posted February 2, 2015 So they still haven't reappeared... but I did notice my pygmy angel looking rough this morning. So I start looking around and I find my rather large emerald crab eating a dead chromis. I think he's been harassing the fish at night, stressing them out, then eating them. This may all be in my imagination, but I removed him to test my theory. Quote Link to comment Share on other sites More sharing options...
Reburn Posted February 2, 2015 Share Posted February 2, 2015 I would banish him to the front yard or down the potty. Here goes Ty on a substantiated crab rant. 1 Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted February 2, 2015 Share Posted February 2, 2015 Haha, actually, emerald crabs are the only crabs invited in my tank. It's the hermit crabs that drive me nuts! Quote Link to comment Share on other sites More sharing options...
BornToHula Posted February 2, 2015 Share Posted February 2, 2015 Same with me, my emerald crab is as peaceful as can be... Hermit crabs, on the other hand, were a snail genocide. 1 Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted February 2, 2015 Share Posted February 2, 2015 Have you thought of the possibility of a fish disease? Uronema? Chromis are pretty susceptible to it. I doubt the emerald is the one to blame. He's just doing his job of cleaning up. 1 Quote Link to comment Share on other sites More sharing options...
Gig 'em @ NDstructible Posted February 4, 2015 Share Posted February 4, 2015 I don't think I've ever seen an emerald crab kill something before. In my experience, emerald crabs are grazing herbivores, and opportunistic omnivores when a nice fresh dead fish comes their way. I would say your chromis probably just died from disease, stress, or something else and you just happened to see the emerald eating his lucky discovery. I find that chromis can be a bit delicate when first introducing to a new tank. I tried adding 6 at once one time to a tank and only one ended up surviving.

Jmvanness Posted February 4, 2015 Author Share Posted February 4, 2015 Looks like I am dealing with disease... ugh. I guess I'll have to setup a ht and run fallow for a couple months. Quote Link to comment Share on other sites More sharing options...
