What Causes This Injury To My Gourami?

Woke up this morning to find one of my honey sunset gourami lying on its side.. it seem to have injured itself and there was a red sore on its tummy area.. a few hours later it passed away and one of my amanos was grabbing it and feeding on the corpse

Just wanna know if the red sore is cause by an injury or is it some disease I should be worried about?

RIP gourami.

 

Are there any fish that could have injured it or sharp decorations?

All was well for the past 3 months and the gourami was the very first fish I added in. No other fishes except for smaller fishes such as green neon and ember tetras. There are 5 amanos in it but they have never disturbed my fishes before except during feeding time.

 

Looks like internal bleeding almost...

How big is your aquarium?

What is your stocking list?

What are your ammonia/nitrite/nitrate levels?

 

If there’s nothing that could have injured it it’s probably internal bleeding like CanadianJoeh said. I agree what’s the tank size and parameters

Just measured my water yesterday.. readings are all safe.




Its a US 10 Gallon tank, with 8 ember tetras, 10 green neons, 2 red robin gourami, 1 honey sunset gourami and 5 amanos.

 

I suspect its death will forever remain a mystery.

 

Perhaps besides the point but that sounds a little overstocked to me, no? Maybe somehow related to the death?

 

Maybe, but the water parameters are good so they have a good maintenance schedule going on. Such an oddity... I don't know what happened to the poor thing.

 

Your fish was likely killed by another gourami. Gouramis are related to Betta's and can get very territorial. Generally they require a good amount of space, and 3 (or I guess you had 4) in a 10 Gallon is WAY too small. Especially with 2 schools of fish as well... :/

Merry Christmas!

 

Oh.. are female gouramis really territorial too? Cause mine are all females.. thot they were doing so well together for the past few months

 

Once they grow up, and hormones kick in, all bets are off. They were probabally small when you got them and now that they are adults they are fighting for tsrritory. If that fish was stressed from being bullied, her immune system was weakened and she could have gotten sick from that.

 

Hemorrhage points towards an internal bacterial infection to me.

Being territorial sounds a bit "strange" to me. When they're in mating mood males get aggressive towards other males (and sometimes other fish) but that is different than being territorial to me.

You don't think they could be stressed with the number of fish in the tank? I know honeys are pretty peacefull with each other, but I thought maybe they just don't have enough space, and it stressed her out, weakening her immune system. You know a lot more than I do though I'm always learning new things on here!

A lot of keepers overstock their tanks, myself included. All things considered, this isn't that bad at all.

mwaaaaa

 

Honey gouramis are supposed to be among the more peaceful species of gourami. I highly doubt they would be attacking each other. If anything they may establish a pecking order and will occasionally show off at each other but it should not ever cause something like this.

I'm wondering now if she wedged herself somewhere and wound up scraping herself, and eventually an infection set in. I just remembered when I did my water changes the other day, I noticed some weird markings on my betta so I netted him to inspect it closer. It looked like scrape marks and I know he likes to wedge himself between hardscapes. So I treated as a preventative for bacterial and fungal infections. It looks like he's healing fine today.

 

I'm concerned that your Nitrates are 0 in a cycled tank. Might be worth testing again.

 

I did the test twice.

 

Alvinkoh, if your tank has been cycling for over 3 months your Nitrates MUST be higher than 0.
Have you thoroughly cleaned your tank? 100% water, gravel and filters?
That's the only way I can get 0 Nitrates!

 

I have never did 100% WC before. I do a 25% weekly WC.

 

something seems off since the tank is overstocked and nitrates are 0.

 

Doesn't add up.
Your tank is quite heavily stocked so after your tank has set up a cycle, you do weekly water changes to keep the Nitrates respectable.
In a heavily stocked tank like yours, this may well take more than 25% weekly WC to keep the Nitrates low enough for your fish to be healthy.
And yet, yours is 0? Really?

 

Do you have a ton of plants? With that full stock I’d expect at least some nitrates. Are you following the directions exactly how they list them? If you aren’t shaking bottle #2 for at least 30 seconds, then shaking the test tube for at least one minute, and then waiting five to compare color then you’ll throw off the test completely.

 

Nitrates are a tricky test

 

Way too much work in my opinion, it also creates wrong results and you get a nice amount of liquid on your hands..

 

So, Alvinkoh, I am guessing you have a Nitrate problem.
Do the Nitrate test again and follow the instructions carefully. Shake, shake, shake!

 

I agree that it could be the bottle and vial hasn't been shaken vigorously enough. However, if that isn't the case, I don't necessarily think having 0 nitrates means the tank is uncycled. It just means the tank is heavily planted or has anaerobic bacteria that consumes nitrates. I have 0, 0, 0 in my tank. Of course, I use media that houses both aerobic and anaerobic bacteria. If the rest of the fish appear fine, then I wouldn't be overly concerned.

 

HI of cuz I shake those tubes hard and leave it to stand for 5 min before I record the results.. lol.. easy instructions to follow. I was shocked at my readings at first also when I did the test a few times. I do have java ferns and monte carlos inside.

Oh I forgot to mention. I dose 8-10 drops of bacter gen.f almost daily..
