Nippy Glow Light Tetra?!?!?!

Ogre44

I have a 29 gallon planted tank with 7 Glow Light tetra and a recently added male Betta.

I just noticed that one of the Tetras is chasing the Betta and nipping at his fins occasionally.
I just added the Betta into the tank yesterday, it's been just the tetras for the preceding two weeks.

It just seems to be the one fish, the rest seem curious about the Betta, but don't seem to be biting or harassing him.

Will this stop?
I bought the Glowlights as they are supposed to be extremely peaceful and good with other sedate fish.

My thinking is that it will only cease when the Betta is removed.

The behaviour of a fish species can be generalized for the majority of the species. But there are often exceptions, just as there are within dog breeds, etc. Science is beginning to discover that environmental issues can cause these variances from the "norm," but sometimes it may just be due to the individuality of a fish.

A Betta is a real temptation to any fish, and many will attempt to take advantage. Characins as a whole are somewhat feisty by nature, so even those we label as normally peaceful are not outside the realm of possibility to nip when the opportunity presents itself.

Thanks Byron, that's what I figured.
I took the poor betta out earlier after I witnessed a particularly vicious attack.
The tetra shot across almost the length of the tank to take a shot at the dorsal fin.

My poor Harvey has just had miserable luck when it comes to tanks and tank mates

Is it going to be safe for other fish in this tank?
I would really like to keep the tetras and add some cories in the near future.

Byron

Corys should not be a problem, and more tetra. Thinking another species, a group of 7 of something suitable, or even two additional species. Perhaps hatchets for the surface? There are many options.

That's reassuring.
I am thinking 7 or 8 of the little Bronze Corys my Brother-in-Law is raising and then perhaps some Neon or Cardinal tetras.
We'll see how the Corys work out first.
