[jungle king]

Hi I would like to know if these are ok for a 30 uk gallon tank after fishless cycle and all that good stuff.

6x Bronze Cory's
6x Zebra Danio's
3x Dwarf Neon Rainbows (females) as eyecatchers

please let me know I havn't got the tank yet benefit people are being slow pokes due to them knowing all about my illness. Got payed double what I get now due to it.

Soz about the lil rant at the end
