Do I Need To Remove This Harlequin Rasbora From The Main Tank?

I'm not sure if he's sick or if he's being picked on.

He's acting just like the others, schooling around and such, and they don't seem to be picking on him at all, but he definitely looks like he's been hurt.

If I have to remove him to keep the other fish safe, the only tank I have to do it in is maybe my ghost shrimp tank. Would he make them sick or are fish and shrimp issues not compatible?

He's smaller than most of them but there are a few others his size too. No other fish in this tank, just these.

 

I think that particular Rasbora has some really bad health issues. The white grows on the back are raised and fuzzy looking, which leads me to believe it's a fungus, other than Columnaris. It's gut is really sunken, which could be several likely incurable intestinal bugs.
Probably best to take that one out asap as to avoid continued exposure to the tankmates.

 

Thank you. I was thinking I should do the same. It's weird that he's acting fine but yeah it's definitely not right looking, and I didn't even notice the sunken gut

 

Shrimp are not effected by many fish issues ,but the treatment for the fish is often death on shrimp.
I agree the rasbora does not look well.

I agree, this seems like a sort of fungus or rot. it will sprend so immediately remove the sick and be on the lookout for more sick fish. He does look a bit weak and I think he doesn't get as much food as the others. I think you should feed him in the QT and see if he eats. Take advantage of him being alone to feed him so that he grows well before you add him back to the main tank. hI might even get bigger than most of your other rasboras in the main tank and he will probably get more food when you add him back to the main tank.

 

Thanks guys

 

your welcome

 

Ok I put him in the shrimp tank and fed him some flakes. He grabbed 3 big flakes and the shrimp stole the rest. Good start

I’m not gonna treat him with anything so as not to harm my ghost it’s. Hope he pulls through!

 

good luck!

 

Got a better pic a few days after switching him to the shrimp tank. He's still acting perfectly normal and eating like a champ. Gets along perfectly with the shrimp too which surprised me a bit. Not sure if he looks better or not though.

 

Columnaris .99%
Clear to see the saddle back as many call this form.
Hopefully the other fish are more resistant in the main tank.

 

he does look a bit better with more coloration.

 

The coloration is hard to compare because I went from T5 in a shaded area to LEDs.

 

oh well it seems healthier still with a more rounded belly.

 

Thanks again. Hopefully he can fully recover in there!

 

QTs are existing for that reason and not just for precation

 

Well in this case a QT wouldn't have mattered much since I got them all from the same tank and shipment 3 days apart.

That said, I'm going to set up a QT after this

 

the best advice in the aquarium hobby is to quarantine your fish and do water changes.

 

Well my dude now has a big white bulge right in the center of his body a millimeter or so before his tail fin starts. It’s big enough to bulge out both sides of him. He’s still acting ok but it’s definitely getting worse. Poor little guy, I’m not sure if I should just put him down or what.

 

I just saw the pic. I'm in total agreement with CB. that looks like a Columnaris infection. The poor fish, as tough as he has been, is being eaten alive by the bacteria. Curing Columnaris is nearly impossible. A lot of meds are available to treat Columnaris, but success stories are very rare. Sadly, IMO best to euthanize.

 

This is the best pic I can post at the moment with the bandwith issues I'm having. Poor fella
