Hi all. I've got an 87 litre tank cycling at the moment and when it (eventually) gets there i'd like it to be a south-east asian blackwater biotope. I've got some nice Asian plants in there (Java fern etc) and a very fine gravel/sand substrate [see pics]. Once stocked I will have: harlequin rasbora, golden gourami and (maybe) kuhli loach. I had my heart set on kuhli loach and would still like to keep them, however, I'm wondering whether they will be visible enough to not just look like i have a few harlequin rasboras and nothing else. What are other people's experience of kuhlis? Are they worth keeping or should i opt for another fish?
