The question is too broad. What species exactly are you going to keep? If you wish to try loaches, serpentine loaches must be avoided. If you could get adult clown loaches, they would be fine. Tiger loaches (Syncrossus) and Yasuhikotakia modesta, despite their massive appearance, however will not make perfect tankmates and are best avoided as these are extremely aggressive fish.superluke;1817568; said:i'm getting a 180 [6x2x2] what do you guys think i should stock it with i want some bichirs possibly
