Found 27th Nov 2008
I got a tropical fish tank and keep finding dead fish for the past week we had about five dead fish.
We changed the water and tested the water and there is nothing wrong with it, any ideas why this could be happening?

it takes a while before you build an 'environment'. Ideally, you should leave the tank with water pump etc along for a few weeks before you buy any fish

OP you're supposed to leave the water to stand for 24-48 hours so the chlorine can dissipate, plus you are heating the tank right? and putting tropical fish in? and feeding them?

Maybe you have suicidal fish - is the enviroment fun for them??

What fish do you have in your tank are they being stressed by any other fish
i used to use KING BRITISH METHYLENE BLUE NO 10 it seams to cure everything and anything in a fish tank

they get fed every other day on either flake or bloodworm, there is plenty of hiding places.

The fish that died were zebra danios and some platys, dont know if they r being bullied by other fish

fish we have are
platys
Zebra Danios
Neons
black widows
3 peppererd cat fish
3 albino catfish
2 clown loach
1 powder blue gourami ( had another but that died)
1 siamese fighter
2 sucking loach

I would more than likely say that they are definatly being bullied, Certain tropical fish cant be kept together due to fighting so you should do a bit or research into that.

Don't listen to any of that absolute **** above - please dont give advice if you dont know what the hell your talking about !!

When you got your tank, you should have declorinated the water, then cycled the tank (with hardy fish or performing a fishless cycle - prefrably the latter).

As you have had your tank for a while, have you done one of the following ?

1. Added new fish ?

2. Changed the water without dechlorinating it 1st ?

When you said your water is fine, can you post your Ammonia, Nitrite & Nitrate stats please, along with your KH & PH readings ?

Also how many Liters does the tank hold.

bullying is the most likily reason, but you can never be sure that your water doesnt have something in thats harmful and NOT being picked up by your water test kits.

It's probably the Siamese fighting fish. I had one in my tank and it killed ~15 guppies and a red tailed black shark

Is their much need to have a go like that i know a bit about fish too just like everyone who has commented! Everyone is entitled to answer the OP question.

Anyway back to topic!

I grew up with my dad having tropical and marine fish and he had a simese fighter and that killed alot of his fish. You could try seperating it away from the others see how it goes for a bit? Then if the fish are still dying you have at least tried one thing.

Have you recently added any new fish?
Do any other fish show any abnormal signs? Any bites or fins been bitten?
Have you dont a partial water change?


Weve had our tank 18months, we test it very regular, and still went through a time where we lost all our zebras and harliquens.

A new fish could bring a disease into the tank...
A fish could be bullying, which was my case... the flying fox thing became very agressive.

Best thing is to sit and watch behaviour... this is how we found out our problem.

thanx we try that, we thought it might be the sucking loach

No problem we are here to help

I just got one of those bio-orb lifes tanks as a nano for a couple of hardy marine fish, I'm into the 4th week of conditioning the aquarium and I have to say I'm pretty impressed with it so far, I thought there may have to be some modifications to the tank but its all going well thus far.

if you just added the fish then it could be toxic shock due to teh difference in water parameters, but if fins were missing then fin rot should be rueld out!! DONT USE METHELANE BLUE in your lovely tank as it turns everything blue there are plenty of others that an be used Melafix is the best its mre expensive than the others but it is for a reason!!

and the live fish willa lways finish off the dead uns there a hearty meal after all!! doesnt mean they killed each other just becuase of that!!

And whoever said that their male fighter was killing their fish thats unprobable they are so deformed they can hardly swim let alone chase others they are usually the ones that get harrased becaue of their finnage, they are called fighters because they fight each other over females

Flying fox are aggressive. He was attacking our fish and they was dying from being bitten or shock.

Its possible one brought disease into tank..

At feeding time, this is why flying fox show aggression... when you feed them sit and watch, my flying fox used to attack at feeding time.... really nasty.

Could be the introduction of new fish has made him aggressive, territorial thing.

IMO they're very shexy lookin tanks, ok I agree most people are gonna get these for the looks rather than to activly look after the fish, but I adore my marine fish and my almost 2 year old seems to be following that passion, so this is her tank for xmas.... I think its important to teach her the value of how much work pets are from an early age :whistling:

ahhhh i thought you meant a bowel you were getting. . . .i quite like the look of that one!! :thumbsup:

Whats it hold?!?

45 litres.......

no the actual Bio-Orb was never an option, i've seen them set up and becuase of the refraction you cant see the fish most the time.

trust me to buy "action-crab" herman the red legged hermit is like he's on speed in our tank, burrows himself in the ceramics one minute then hanging off the tip of a plant the next lol.
