Advice 4 my sisters new tank

[pandapops001]

Well she has a 15gal UK, she cycled with 2 zebra danios, and now wants to add 3 neon tetras
3 bleeding heart tetras
3 black neon tetras

I've told her that she will have to add them gradually, say 3 a week depending on her water, and i tested her water and her perimeters are nitrate 10, nitrite 0, ammonia 0

After telling her this i thought that i'd better check with yourselves, will these fish all go together and that it wont be overstocked

Thanks in advance guys

All the fish will definately go together.

Also depending on her filteration and how many water changes she does a week, she can add 6 neon right away. Their bio load addition will not upset bio filter, and its better to keep 6


BUT SHE MUST DO WATER CHANGES!

i think she has a fluval 2 or 3 not sure, yes she is used to the water changes thing now.

I did not realise you could add 6 neons at once, oopps, dont think she'll be happy about my misguidance lol

It doesnt have to be 6 of the same type of tetra though does it, i thought most tetras would skool together ??
