dead fish

I cleaned out my tank and pruned back some of the plants, sucked the gravel, and changed the HOB filter elements. Tank also has an undergravel filter. A pair of discus in the tank spawned (on the heater which obviously was not a good choice) the next day, so things must not have been too "off"...

Treated 10 g quarantine tank with 0.6 g 99% pure levimasole HCI powder (recommended dose per Subquaria where it was purchased) to rid of callamanus worms. Within an hour 3 previously appearing healthy red rasbora were dead, the sick black neon tetra with worms dead too, the rest distressed...

Hi everyone, this is my first time posting but I've been a long time lurker. I've set up a heavily planted 10 gallon aquarium. I used to have 3 kuhli loaches and 6 pearl danios in it, but when I added a dozen sakura cherry shrimp to it, the danios would aggressively tear at any of the shrimp...

I have a 30 gallon set up that has been going for a little over a year. Things have been going well recently except a few fish have come down with the same symptoms... First it started with one of my diamond tetras a couple weeks ago. He was swimming funny, doing loops around the tank like he...

About 2 years ago, the tank I have labled as saltwater was freshwater and had started with barbs. The barbs weren't working for us, so we waited a little longer and then bought 3 mollies, 1 male (seemingly a cremecicle lyretail, according to petsmart), and 2 females (a black one and a sliver and...

I have a 29 gallon Oceonic Biocube that seems to be a death trap. When the Scooter Blenny died I was thinking starvation, then I fought a Mantis Shrimp for the remains of a healthy Tailspot. At that point I believed the Mantis was the problem so he was removed. Within days the Saddleback...

Hi and thank you for trying to help me on this thread. I have a 10 gallon cold fresh water aquarium with gold fish and one african dwarf frog Today i found 3 fish dead with a light white fuz around them. My frog has only its leg surrounded in this white fuz. Can anyone help me with...

Hello all, Brand new to this forum, glad to find it. I've had a Betta for a while now in a 1 gallon tank, I bought him at a Petsmart and upon doing a bit of research I found a 1 gallon was WAY too small for him. We'd been talking about getting a 'real' tank, so Friday night we went to an...

I just bought 8 neon tetras but they all just died in the course of five hours!!!!!!! I tested my water and it was perfect so it wasn't the water quality . If you have any idea why they all died that would be great!!!!

any help is appreciated. I have had an established aquarium with one electric blue african ciclid for over a year. a few weeks ago i added another and things were going good so i bought another (orange african ciclid). it did not fair well against the others and was huddeling a lot. 2 days later...

I'm super busy tonight and I came home from school to a dead Australian Rainbowfish and a really loud filter. I changed my filter and added more water into the tank but this didn't solve anything. The biowheel seemed to be moving somewhat slow. I took a cup and scooped water and poured it into...

I have a month old aquarium, so I guess you could say it is still a "new" tank. It's a three gallon tank. I originally tried to start off with some easy fish because I am new to the fishkeeping hobby. I got two glofish and a dalmation molly. The molly had babies, but I got rid of all of them as...

I attached for you some pics of my dead molly fish hoping u can idetify the cause of death and hopefully help me save my fish I have a 60*40*30 cm tank I only raise Mollys I have about 20 fish all are from the same family (original parents died) but several generations the died fish is a female...

It's obviously too late for this to help due to the fact that I woke up this morning and my green terror that I purchased on thursday was already dead. I'm trying to figure out why it died so I don't go throwing another $20 down the toilet...literally. I have a 45 gallon hex tank housing a very...
