Recently I realized that I want to have a tank with only loaches. I had a discus tank, but since I am a student, I have no time for everyday water changes and vacuum cleaning
That is a 40gal tank. It will be heavy decorated with lots of wood, planted with large quantity of short plants (anubia batteri var. nana) and maby a big amazon sword.
...And now the questions (about stocking)...
1)So, clown loaches grow up to 12 inches. That is too large for a 40gal. But however, I heared that people keep them in smaller tanks, because then they don't grow to their full size. So, the question is can I put them in 40gal, and how many of them (a tank with clowns only)?
2)The same question as the one above, just about YoYo loaches : how many YoYo loaches can I put in a 40gal tank (YoYo species tank)?
3)Maby the best option is to have a tank with clowns, YoYo and Botia Striata. Is it good to keep this 3 species together (do they get along), and also what number of each would be the best for 40gals?
...Maintenance questions...
4)How many water changes weekly would fully stocked botia-only 40gal tank require?
5)IMPORTANT QUESTION, HELP REQUIRED : my tank will be filled with driftwood.That means that vacuum cleaning will be impossible (I can't reach the gravel because it is allmost completly covered with 15 pieces of driftwood!!!) Now if I don't vacuum the botom, a lot of waste will collect there and spoil the water. But however, loaches dig alot. Will their bottom-activity be enough to keep the tank a healty place even without vacuum-cleaning? And if not what should I do? Taking the wood out is not an option! It looks so good

Sorry because long post but I want to know....
Thanks
