I've been reading profiles for the Dojo Loach. I have seen three of sites that suggest a 30 gallon is large enough to house three. However, I saw another site that said a minimum 100 gallon tank was required. That's a huge difference. So I'm wondering how large a tank they actually need. I'm stocking a 36" 35 gallon tank and I'm wondering if I can keep 3 dojos, possibly with some Bleeding Heart Tetras and Harlequin Rasboras.
