Black Widows And Silver Sharks

[rossyboy]

Does anyone know anything about these?

I admit i should have done more research first, but i've got 5 black widows in my 80Litre setup, with a few other species.

The shark seems to chase these around quite a lot, any reason? Other than a dwarf gourami they're the biggest fish below the shark in the tank as i have Harlequin's, silver tip tetras and neons also.

Here they are incase the names i've given are UK 'nicknames'

Black widow's are awesome fish. There more commonly called Black skirt tetras. I have a couple of the long finned variety where all the fins are large and flowing. Also bala sharks need to be in a much bigger tank. I think they need 150 gallons. They grow to 12 inches and need to be in groups.

Here's is a pic of the long-finned variey.

Oooh those are beautiful with the longer fin.

And that damn pet shop keeps selling me back stuff lol, that shark he said would be fine. should i wait till it grows too big or just take it back now?

You should take it back now because if it becomes too big they probably wont take it back.
