What rainbow fish ?

 

[WILDER]

Do you have plenty of hiding spaces, can you post water stats in ammonia,nitrite,nitrate,and ph, plus shouldn't keep two red tailed black shark together as they can't tolerate there own species, plus how many rainbow fish do you have.

 

[grumpymole]

not sure with water stats, but have two rainbow fish

 

[WILDER]

How long has the tank been set up, as poor water quality can make them act aggressive, though the tank is a very good size.

 

[Bloo]

it would help a great deal if you could tell us what Rainbow fish they are ? There are very many and they all differ.....

Any chance of isolating these two fish ?

 

[grumpymole]

tank has been set up with fish in for about 2 months now, is this not enough?

yes that is what ive done temporarily, they are in my (gulp) fish tank

 

[WILDER]

no, they are not cichilds.
in fish shop they called them just rainbow fish, and that was it
but they dont look anything like them
the ones i have are completly yellow

 

[WILDER]

Not meant to be agressive according to this site, i would do a water change just to make sure it isn't water quality.

[grumpymole]

thats them
i have already done water change
cant change water too often though as tetras gnerally preffer 6 week old water
they are still aggresive
i was wondering if one was pregnant?

 

[grumpymole]

(not to subject but oh well)
do u guys know any large community fish that would go well with my tank?

While you're talking about aggressive fish...

2 red tailed sharks

That's a problem waiting to happen.

I assume they're both juveniles, or you would have seen it already, but you really only ought to keep one RTBS in a tank.

I seem to be saying this a lot at the moment.
