I've just had to temporally re-home some Barbucca sp's this evening! I dug up this old 20gal especially for these loaches and maybe a few others that i might come across in the not-to-distant future. The old tank in question lasted 5 weeks filled with water..etc.. before it decided to pack up! The crack isn't visible from the sides as it was a base crack that decided to give in. Grrrr.... I bet the wife or one of the kids dropped it or something! It's not nice seeing a half-full/half-empty tank with water everywhere around it.
On the plus side! I did manage a couple of pictures of these little chaps in their Temp home.
Good luck with the tank.
At least they are safe and well.
