Michael7979 Posted June 3, 2008 Share Posted June 3, 2008 We started a 11g Via-Aqua tank for the wife about 1 1/2 months ago. Cycled it with old water and some rock from my "holding system" tank. Keep a few damsels in there until she found the fish she wanted. So last week we found 3 Marginate damsels. Put them in and removed the other damsels and all was good. Until today........ woke up to find all 3 dead!! Give me some ideas why???? Maybe I'm forgetting something. Quote Link to comment Share on other sites More sharing options...
andy Posted June 3, 2008 Share Posted June 3, 2008 Tank params? Quote Link to comment Share on other sites More sharing options...
Jay Posted June 3, 2008 Share Posted June 3, 2008 Yep test the water and post the results. Also thats a small tank...keep the water changes going weekly or bi-weekly. Jay Quote Link to comment Share on other sites More sharing options...
Jay Posted June 3, 2008 Share Posted June 3, 2008 Is there a heater? Mabey it stuck in the on position. Happened to me once and my tank was 88 degrees before I noticed it. No more heaters for me....that was before I had halides and now the problem is keeping it under 81 most of the time. Jay Quote Link to comment Share on other sites More sharing options...
Michael7979 Posted June 4, 2008 Author Share Posted June 4, 2008 I'll will have to take new test readings but they were acceptable just a few days ago. No heater and no problems with keeping it at 75-78 degrees. Starting to think something got into the tank........ some form of spray or something.

Guest Snorkelwasp Posted June 4, 2008 Share Posted June 4, 2008 my idea would be that maybe one died and set off a chain reaction to the other 2 via ammonia spike Quote Link to comment Share on other sites More sharing options...
andy Posted June 4, 2008 Share Posted June 4, 2008 They were eating well? No weird behavior? Quote Link to comment Share on other sites More sharing options...
Michael7979 Posted June 4, 2008 Author Share Posted June 4, 2008 They were eating well? No weird behavior? Yes and no to the 2 questions. Starting to think it may have gotten too cold overnight since I'm trying to run heater-less. Can't think of any other reason. Quote Link to comment Share on other sites More sharing options...
andy Posted June 4, 2008 Share Posted June 4, 2008 Perhaps they took some kind of hit during collection or transport. All three going at once strikes me as pretty odd. Quote Link to comment Share on other sites More sharing options...

Yeah that was my first thought too. "why all 3 overnight?" I may never know. (scratch)(scratch) Quote Link to comment Share on other sites More sharing options...
Jay Posted June 4, 2008 Share Posted June 4, 2008 Too much flucuation in temp is hard on fish for sure but those damsels are pretty hardy fish. What ones were they? The domino or convict or blue with yellow tail? I had a domino damsel that grew really big and was the biggest bully. He died durring transport from moses lake. His bag was touching the heat pack in the box. Not bad to only lose one fish and 1 starfish moving from moses lake n december 300 miles in the back of my pickup going 75. What a pain in the rear that move was. I stored my livestock at seahorse aquarium for a month while my tank cycled from the move. Thanks again Woody for letting me use 1 of your big sections in your tank to keep them. Have you painted inside your house? I bleached my corals and caused infections on all my lps corals last year after painting my liveingroom without turning off my skimmer. Man did that day suck...running all over portland looking for 55 gallon drums and buying premade saltwater to do a emergency 100% water change 120 gallons. Yep sucked bigtime.

Michael7979 Posted June 4, 2008 Author Share Posted June 4, 2008 They were the Marginate (sp.) damsels. Nope, no painting. Quote Link to comment Share on other sites More sharing options...
mrgreenthumb Posted June 5, 2008 Share Posted June 5, 2008 Hmm what about chlorine or chloramines? Or dissolved oxygen? Seems these two are often overlooked. Alot can happen in a couple of days espically with ammonia and nitrite. I would double check those params before anything. Could just as easily have been where and how the fish made it to your tank from the ocean. Quote Link to comment Share on other sites More sharing options...
pledosophy Posted June 5, 2008 Share Posted June 5, 2008 Can you post a pic of the tank from far enough back to show all the equipment so we can see how it is running? 3 at once is a spike in a level, a chemical being introduced, or lack of oxygen IMO.

Michael7979 Posted June 6, 2008 Author Share Posted June 6, 2008 Water tested OK. Water getting cold isn't an option now as it only gets done to 74 degrees. Had 3 fish in the tank for along time so I don't see that as being the reason either. Quote Link to comment Share on other sites More sharing options...
