Right...
small tank is outta comission due to my new house is cold

and it's not suitable for a heater
medium tank (15 - 20gal) =
5 full grown Cardinal Tetra
5 full grown Glowlight Tetra
adding:
4 Corydora
1 Betta (on trial basis, will buy him his own tank if the Tetra don't like him)
big tank (90gal)
2 Dwarf Gourami*
2 Pearl Gourami*
6 Zebra Danios *
6 Leopard Danios *
6 Pearl Danios (the Danios are so playful! I like em) *
4 Lake Kutubu Rainbow*
4 Pencil Fish
5 Corydoras*
1 Bristle Nosed Plec*
2 Kuhlie Loaches
(please note I do not want
ALL of these, they are what I like, I'm just not sure of compatability)
I'm also thinking of going for sand/fine gravel substrate and lots of mixed planting round the back and edges with some low-lying central ones, to give plenty of hiding places for the Gouramis to have space and avoid territory disputes.
Will different Danios school with each other? if so I would probably drop to four of each
the ones with
asterisks are the ones I would really like but do you think this would work?
(all Gallons are UK)
