The tank is 110cm x 45cm(depth) x 58cm(hight). (It's a Ferplast Cayman 110 of 230 liters/60 gallons)
I was thinking about two groups; one group of 6 Botia histrionica and the other a group of 6 Botia almorhae. Are these group sizes possible in my tank size?
The other option is one larger group of Botia histrionica, but I think the maximum group size might be about 8, or is more possible with this Botia? It's supposed to become a Loach specific tank, so there should be an interesting number of loaches in it in order for the extra fish to stay just that, extra.
