Hi All
My names Dave, just joined the site this weekend.

Been keeping fish on and off for about 5 years now - with some success and some pretty epic failures!
Ive just started up a 60 litre biorb tropical freshwater

Its been cycling for 5 weeks now, last week I introduced 6 Neon Tetras - after no fatalities and everyone settling in comfortably I decided to introduce 6 Harlequin Rasboras on Saturday.....

All hell has now broken loose! The rasboras are now speeding around the tank in shoal formation (literally around it in a corcle given the shape of the tank) - the Neon Tetras seem to be a bit stressed and unsure what to do with themselves - one or two try to shoal with the harlequins, the others hide. I have not seen them all together since Sunday evening.

One is now also swimming pretty erratically - i have tested the water myself and also had it tested by my retailer on Saturday - PH nitrate and ammonia were all fine & still did a partial water change Sat evening after addiding the new fish.

Getting worried about fatalities and the welfare of the neons - anyone have any ideas what i should or can do?

Maybe the community will settle ina few days?

I have kept the species together before with no problems.

Any advice would be great!!


Nice to meet you all,

Dave.

Welcome Dave.

Can you place a tall growing Plant or Plants in their path to break up their gallop?

Kev.

Hello and welcome, newish on here myself, just starting back into the hobby. Looking at getting tetras and harlequins myself. I think Kevs idea is a good one, even a plastic plant for a few days to see if it breaks things up a bit in the orb!

Welcome along mate, hope all settles down for you soon.

Thanks folks!

Things seem to be settling down a little bit - they all seem to be shoaling together now which isnt so bad. I took the idea of breaking up their circuit by repositioning a plant (plastic) and they seem a bit calmer.

The neon that was swimming erratically also died at some point today and another is now the same but not as bad. Temperature currently 26C and water stats seem fine.

Any ideas?? Stress????

Thanks guys

welcome along mate
