I have a fin-nipper. A truly evil fish masquerading as a regular finny critter.

It drove my betta into the filter (to his death,) and it ATE quite a bit of my smaller black phantom tetras, whom I had to euthanize. It started with his tail and top fins being eaten off, then the whole back 1/4 of the fish was missing.

Now, my littlest remaining black phantom has had his top fins and tail eaten off.

I have my hospital tank set up and ready to go ... is it worth it to pull the littlest phantom out and stick him in there all alone? To remain in the big tank is certain death, while I wonder about the stress for a shoaling fish being alone. I will not put any buddies in the hospital tank, because I might inadvertantly put the culprit in there.

WWYD?

Do you know who the evil fish is ?

It shouldn't be a problem, I've had tetras alone before and they've been fine. Seemingly even better than when I had a group...

id say the stress of it being in the tank with the bully is probably worse than being in .a tank alone. obviously just keep a look out for the culprit then seperate it. what fish do you have in there apart from the ones mentioned

If I knew who it was, THEY would be the fish getting euthanized!

I have 4 danios, 5 black phantom tetras (remaining) and 1 cory.

This weekend I will bring in more fish -- buddies for the cory at the very least.

But, interestingly, over the months that I have had them, some of the danios and some of the tetras have grown HUGE. Some have not grown that much. I suspect the bigger of the tetras to be the bullies, but I can't PROVE it.

dont mean to be funny but your last post seemed very aggresive when someone was only asking a question. from your first post it did read like you knew which fish it was but just hadnt said. i may have misunderstood the way you worded it but people were trying to help. i wouldnt suggest adding any new fish until you find out which it is, not even add corys. the fish will probably be stressed as it is from being bullied without having to deal with other fish aswell. i may be wrong and someone may think it'll help the situation. you also risk losing the new fish as they will be stressed from moving tanks and add the bully aswell and id say its a huge risk, but its up to you and like i said i may be wrong and youve probably thought of this anyway.

hope you dont find my comment offensive it is meant as constructive criticism in the way you word posts to avoid getting peoples backs up in the future

LOL!!

Sorry, didn't mean to come off as aggressive, just funny.

I get the idea that perhaps I am quite a bit older than many members, so perhaps it's just a different method of emphasis?

Anyway, I am fairly new to fishkeeping and am asking advice on any and all topics.

I was unable to corral the tetra (the tank is waaaaay to big for me to get him without netting him, which I believe is too stressful.) So, I am keeping an eye on him and so far he seems to be OK with no additional damage. I am watching to make sure his fins begin growing back.

Anyway, thanks for the hint about tone.
