3 Black Widow Tetras In 48Litre

[ladybird76]

My tank is fully cycled and I have 3 black widow tetras. What else can I add? I'd like something red or maybe blue to add some colour??

more black widow tetra - all tetra prefer to be in larger groups with 6 being considered the absoloute minimum

Agreed. Black widows can be very nippy in small shoals, so anything else you put in could come in for some harrasment too.

Yeah black widows are nippy i did have 4. One of my favourite. Get a few more.

Why not add some corrys??

 

[fluttermoth]

Don't you think 10g is a bit small for cories? I do...

 

[Tizer]

too small

 

[swanseastilo]

What size would you recomend for corries then??

 

[Blubble37]

you could get dwarf cories, theyre small and shoal

20g minimum IMO

Dwarf cories would fit in, but I think the black widows might be too boisterious and/or nippy for them; they're quite shy.

 

[Blubble37]

i find that the dwarf cories become less shy when kept with other schoaling fish, try some neon/cardinal tetras, my ones love to sociallise with them!!!

I just had a look at some cardinal tetras and I love them! The only thing I was wondering is how important is the pH? On one site it read that the pH should be between 4.0 and 6.8. My water is a constant 7.6

Get more black widow tetras or else they will be very nippy to whatever other fish you add.

I would be happy with 6 corys in a 90 litre tank, as long as it was 2 foot long.

I would be happy with 8 dwarf corys in a 70 litre tank but i would still want it to be 2 foot long with less height.

I woudl not put corys in anything smaller.

I would not put corys in any bi0rbs, fluval chi's, fluval edge, hexagonal tanks and i would most deffinately not use any sort of gravel even if it was very small and smooth, for me, its sand, or bare bottom.

Cardinals will live in that water, but that will probably experience a reduced lifespan. They do better in softer water.
