How often do fish die in your tanks?

Other than accidents, like my moving fiasco, most of my fish seem to be fine. I may lose one or two every so often, but most of my fish are several years old now. Several people have pitched ideas that seem like they might be the underlying cause of your problem. Good luck :)
 
hello

responding to the first post will read the thread after

I would recommend increasing the amount of water you change to at least 30%-50%/ week. Personally I do 50% and 2-3x50% on my tanks over 200g.

For water conditioner I find that the biggest bang for the buck is seachem prime since the volume treated per bottle to the cost of bottle ratio surpases any other product in my mind.

I am also a big fan of moving air in my tanks, while there are those who say having a bubbler does nothing, I find a good airpump and diffuser does increase flow in the tank and have done tanks without and with just to compare with the only difference being the addition of the air and I find that my fish are much more active with air in the tank.

I lose fish to agression not so often but it happens, I just lost a loach that swam into the intake tube of my filter and promptly died. I noticed it when the fish started to breath hard, did an inventory and sure enough he was dead in the tube (aside prime will enable you to nuke any inflated water chemistry levels without harming the fish in such a case as this).

And of course I lose fish to getting eaten by other fish since fish eat fish.

There is also the rehoming factor when I take fish from other peoples set ups where the water condition is shall we say not the best. For example here is a picture of the set up that I just took the remaining fish out of the other day

this is one of the fish, a jack dempsy without normal coloring

In all cases I find that a regular large volume waterchange keeps the fish happy and alive for longer.

edit:another suggestion would be a regular monthly cleaning of the filter housing and tubes, with the sponge being squeezed out in a bucket of tank water to clear it of excess waste and the filter being cleaned with a brush for a dirty filter will defeat a waterchange any day
 
I haven't lost a fish in over 2 years and even then it was to aggression. But I keep larger, hardy fish. Some of my fish are pretty old too. I've had my Florida Gar and Jaguar Cichild for over 8 years and some of my koi I've had for 14-15 years.
 
In the past 3yrs ive lost 1fish and that was due to poor acclimation on my part but also like Vicious I keep hardy fish.

Nice New Avitar Vicious
 
I have been reading this thread and it has made me realize that every single fish that I have lost came from a particular store. I have lost some neons pretty quickly after I bought them, a rummynose tetra from Ich (the other 2 made it) 2 sterbais and 2 peppered corys. Oh and my betta, but that is a different story. All of my other fish, corys, rasboras, and neons all came from petsmart and have been with me since the beginning! I got some otos from this forum and some embers and they are wonderful also. I have been having some recent problem with losing my pea size briggs and am starting to wonder if my ghost shrimp are killing them. All the big ones, teens and tiny babies are fine but I find pea size shells once in a while. Strange.
 
I don't remember if you mentioned this, but what testing equipment are you using. Test strips are totally unreliable and inaccurate most of the time. A good liquid test kit like the API Master will give accurate readings, unless it is old and may have lost some of its effectiveness.

Ditto on the PRIME. It is HUGE in my book.

I have a 10 gallon and haven't lost anything in quite a while except a guppy I had to euthanise due to septicemia. About four or five months ago I had a mishap with chlorine poisoning and lost three neons, but had everything else ride through that episode. I dosed Prime immediately when the first two fish rolled over.

I do 65 to 80% water change at least once a week, and sometimes every three to five days if I see uneaten food or gunk sunk down in this stupid epoxy coated rough gravel. (am changing to sand ASAP)

I'm treating my tank for Ich right now, with no losses, and only one fish showing the specks. I'm nearing the completion of the treatment process.

I have as mentioned: 10 Gallon, 1 Brochis, 2(very hardy) Ottos, 2 ADFs, 2 ghost shrimp, 1 large Bridgesii snail, many tiny hitchiker ramshorn snails, live plants.

I've had the tank for a year and was a total noob. I lost several fish over the first three months but things settled down after about four months.

Sometimes I can go for a long time many months with 0 losses then something will happen and I will lose someone. Sometimes it is my fault like I know I should have done that water change but I stretched it out "one more day" and woke up to a death or something else foolish but sometimes it will just be a " what the heck" I don't know what happened.
 
I have had some of my fish for years, and others die randomly. I kept guppies for a short while but they kept dying - I think it was purely because of the LFS stock, the others all seem fine. I don't keep guppies anymore and the rest of my fish are all happy as can be. Maybe try find a different supplier?
 
About a week ago I lost 4 cories in my 29 gallon tank because I cooked them. The rams were happy with the high temp and the guppies all survived. These are the only fish I've lost in a long time.
