I have the 3 clown laoches, in a 20 long gallon, ranging from 1-1.5 inches. I have had them for 6 months, and they have become my favorite fish, and loaches have become my favorite type of fish. Now here comes the question, my friend is redoing his tank to an african tank next week, changing to the sand I have, making more caves, getting an extra filter, and the cichlids. Would the 3 clowns be happy in a 85 gallon till I can get a bigger tank? Or can they stay in my tank? Taking them back isnt an answer anymore.
