A couple of months ago I set up a tank especially for a small shoal of Harlequin Rasboras. When I feed the Rasboras, some of the food inevitably falls to the bottom of the tank which I have to remove with a net. Can anyone recommend something small I can get that will share the tank with the Rasboras and feed on the pellets and other bit of food that falls to the bottom of the tank? I'd thought of Kuhli Loaches but as I have no real dark places for them to hide apart from the Hairgrass, I doubt if they'd be suitable. Having always kept a number of tanks for fancy Goldfish, food falling to the bottom of a tank has never been a problem before.
