Chubster The New Mandarin--Dead.

Well, I have no clue what the problem was. As some of you have read; Chubster was a brand new spotted mandarin addition. He was purchased on Feb. 15. He was eating great at the store, and in my tank too. Within 15 seconds of adding him to the tank, he was wolfing down 'pods.

The only thing I found strange was he was a swimmer. I have no experience with mandarins, but I read up on them real well before buying one. I know they require 'pods. I also know from experience in seeing them that they tend to be bottom dwellers.

Well my Chubster was always eating. He never appeared stressed. My other inhabitants are two banggai cardinals, a skunk shrimp and a modest cleanup crew of a few nassarius, blue legged hermits, and cerith snails. I own two corals, a mushroom and zoa-covered rock. They look fantastic. The mushrooms are already growing and reproducing, even. All in all, the tank continues to do very well.

My water quality is great. Ca is about 450; Alk is 11.2, no ammonia nitrates or nitrites. pH is spot on at 8.4.

Maybe somebody with more experience with mandarins can tell me if they ever swim. Chubster swam quite often. When he swam, he never appeared stressed. He seemed to like "riding the waves" that the Vortech produced. He was always eating. Every time I looked at him he was slowly migrating around and in between LR, sucking down 'pods.

My skunk shrimp always tried to latch on to him and clean him off. He seemed to tolerate it, but was clearly none too pleased. He usually gave the shrimp a few seconds to pick around on his fat body, and kinda walked away.

I have no clue what went wrong. Every other tank inhabitant shows no change in personality. Last night, I looked for him for a few minutes, didn't see him, and reluctantly grabbed the flashlight to spy the nether regions of carpet behind the tank. The pulse started to go up in anticipation. I've seen this before. Yup. There he was. Looking just like a letter C. I found Chubster on the carpet dried up and lifeless.

I'll never have a top on my tank. I want the O2 exchange and don't want any light obstructed by salt spray on a glass top. I've been picking my fish very carefully with a "no jumpers allowed" policy. That's why I don't get a firefish, which I love. They tend to jump.

So? What am I missing? Was the fact that Chubster swam, a warning sign that I should have realized meant something important? What's going on here?
 
I had a few fish jump from my tank that are not generally known as habitual jumpers, shortly after introduction to the tank (within days) and it always happened in the middle of the night.

I discovered I had 3 large blackish predatory crabs that were hunting at night and I imagine startled the fish.
 
In it's natural habitat, a mandarin can jump all it wants because it knows it's going to land in water.. Do your fish a favor and put a lid on it!! I wipe down my lens every week and the salt doesn't even build up. Try directing a powerhead toward the surface for air exchange/ agitation....then feel free to put in your firefish!!! It's a win win....
 
my mandarin is always swimming around. and the one time he managed to get into my sump he jumped over baffles to get to my refugium, so im not too surprised by this. but you'd never convince me to have a lid, they look kinda ugly, they reduce light, increase temps, and its another thing to clean.
 
I'll agree on the swimming of the mandarin. My little one swims like crazy, and is always out and about after lights out, fluttering in the current.

I've lost a diamond goby due to jumping, who was in the tank almost 6 months before he jumped. I now have glass tops, but I have a sump below. I wipe them down at least once a week, cleaning with vinegar to get off a lot of the salt.
 
Fish jump. Some fish jump more often than others. No cover, means carpet sufing is an issue. And, by the way, egg crate does not work.
 
i have used egg crate in the past thinking it would be better than completely closing off the top. Apperently fish that want to carpet surf also got great aim. if your fish can get through they will. I think your first mistake was naming your fish, first rule in this house- dont name the fish! if you do they are to be short lived. lol
 
You could try to find a kind of mesh netting that had some clear fibers. Sorry, I can't recommend a specific website or product.
The closest thing I know of is a mesh netting sold by pond websites to cover ponds with koi in them, but the holes are almost the same size as the eggcrate light diffuser and the material is black.
 
FIsh tend to jump looking for better water conditions.Also have another tank in view may incourage them to jump to it.
I didnt see any powerheads listed or mb 1.
 
Just to be devils advocate, I've had my 58 uncovered for years, with a mandarin, and the only carpet surfer I've ever had was a bartletts anthias. It was harassed out of the water by my demonspawn jeweled blenny, I'm certain. I don't run egg crate. I do have a sorta ghetto open top canopy substitute that sorta encloses three sides (sorta being the holes cut out for plumbing). Never the less, there's plenty of room for carpet surfing. But I have an insanely oldschool dense rock warren in my tank, there's around 140lbs of live rock in there, built into a winding series of caverns and pathways where no eye can pry. The fish love it, I'm used to it, guests are appalled. IMO, having places to hide make the fish less likely to jump.

Oh, and I don't name the fish either, except for the Dragonfish (aka blenny from Hades) because well, he's evil enough to withstand the jinx of a name.

Sorry to hear about Chubster though. Mandarins do tend to swim and jump a lot. If it's any consolation, was probably a sign of health. Sick fish aren't too energetic.
 
SW fish are very smart. If they approve of there surrondings ,like water quality , other stock , and rockwork with lots of safe places to call home , they would perfer to stay. Thats not 100% though. There are dumb or maybe smarter fish who just jump for no reason or those looking for an adventure.Glass half full or half empty thing.
They are more prone during interduction from other fish sporting there muscle. Add least aggresive fish to most to help this.

Tremendous speculation on your part. Whether or not fish are smart is debatable. I don't have any other pets who will poop, turn around, eat it, not like it, spit it out, and after 3 seconds do a replay. Also, to say that "if they approve of their surroundings. . " etc, carries with it an assumption that jumpers are "trying to get out," as if they have this feeling that conditions are somehow different somewhere else. I'm not so sure that fish even realize that close to that "sunlight" lies an environment devoid of water. But who knows? ? I have a suspicion that fish are probably not "looking for adventure" as you speculate.

I'll agree that they're more prone to jump at introduction to the tank due to harrassment. However, statements like "FIsh tend to jump looking for better water conditions" is nothing more than pure conjectrure. Truth is neither you nor I will EVER know just why fish jump.
