death

I have read recently - that dinoflagellates 'kill corals and fish' - I noticed (after months with none) - and after a failed alkalinity doser that some parts of a couple corals died off - On those dead places - some dinoflagellates have started growing. They are not on any other rock, etc -...

Hi there, I am a researcher, and I need to know why do the color of fish change when they die? What are some of the scientific reasons? Thanks.

It all started when I added a midas a few months ago and ever since then any new fish I add to the tank will always die after a week or two however it does not affect inverts. The symptoms displayed are a reduction in appetite but still eating and gently pacing the glass. At the end the fish...

Hi everyone! So on Monday night all my fish died except my electric blue hermit crab. So sad. My tank was established on May 10th of this year. I was doing the BRS 5 minute video set up. So far so good ~no issues until now. In my tank we’re 2 pairs of clown fish and the blue hermit crab. Monday...

So, I did something foolish and my poor puffer had to pay for it. I was performing a tank transfer(no discussion about TTM, please) with my Valentini puffer and a few other fish. I bought a second Penguin 200 as a filter, but it was missing a piece on the intake, so I couldn't attach the...

Hi, I recently added a couple chromis to my nano tank and they sadly passed away very quickly. I cant imagine it was due to water quality or acclimation. Took a picture of one of the chromis and seemed to have black spots on the face. No idea where this disease could have come from. My clownfish...

I know know - My polls are long and everyone hates them - but... Theres more - here is another short one - Have you ever had a coral RTN, STN, etc etc etc - other cause of death - which has come back after the fact. I have had a couple of late after a tank mess come back 3-4 years later - so...

Hi everyone, I hope everybody is doing good. I have some questions about marine ich, I want to separate fact from fiction so if you can help me out I’d very much appreciate it. 1. Can a fish have ich and not show any signs of it? 2. I’ve been told a fish can carry ich and not show signs of it...

This is mostly a vent about my stupidity. momentary lack of awesome. So I tend to run my pH on the high side (8.5 - 8.6) and everything was looking great. At some point it started to creep close to 8.75 (Tested with Apex, Profilux, and pinpoint. New probes and calibration to confirm) Suddenly...

I have a 9 month old tank. Last week I turned off my return pump overnight due to a plumbing problem. I have a refugium with lots of macro growing in it. When I turned off the power for the return pump, it also turned off the light in the fuge. I fixed the plumbing the next day but noticed the...

Help! I have two clownfish i bought a month ago. The larger female always takes the pellets i drop in while the smaller male gets nothing. I thought i would seperate then to feed them but then my make clownfish is so deprived if food he doesnt come out of his hidey hole(which is a small gap...

Hi , just wanting some input from anyone who has experience owning or who knows about this type of angelfish ? (Heralds angelfish) So I think my angelfish is killing my skunk shrimp .... the cleaner shrimp have been in the tank for two months with no issues both of the shrimp suddenly died 2...

Hey guys. So I'm going to start this out by saying I'm a new reefer who's just received their first shipment of coral frags from WWC. When I received them, I floated them in my QT tank water for about 20-30 minutes. Then, I prepared to remove them from their base. This is the first mistake I...

Before I get into the idea of a tank tear down and my plan; let me give a little back story. I bought the Bowes front acrylic tank used. Kept all the same water and sand. I’ve had the tank for approx 1.5 yrs and have done a lot to it. It was just 3 large pieces of rock, a couple fish, and an...

Alright. I don’t understand. I got this guy over a month ago. Had been GREAT! Good appetite. Good color. Never a sign of sickness. I don’t get it. Water parameters are great. Anyone see anything from these videos?

Hey Guys. I’m a brand new reefer who just set up his first system with a 75 gallon display and 30 gallon sump. I’m using marine depots DL-800 skimmer box in my display tank. Anyway, a couple of days ago I added in a pair of clowns. They were both doing great, and eating well. Then one of them...

Hello, I have been having issues with keeping SPS in my tank. It seems to bleach and die very quickly every time I give it a try. I have many things doing extremely well in the tank such as bubble coral, JF JOL, torch, various nems, duncans, GSP (I know this stuff would practically grow in the...

so I just started a 30 gallon marine tank fee live rock and filter skimmer etc. so at first I put a 6 line wrasse (I know their mean) to get bio filter going and to see if how he would do. He was doing great. I added the antenna lionfish that I originally wanted he's doing fine too. Then this is...
