Okay, I have three Clown Loaches that are going to need to moved to a bigger tank before long. My parents are remodeling their home and my father wants to respark his aquarium hobby with something like a 55 gallon Discus tank (he had a Discus tank before and I think he misses it!). Anyway I was wondering if a 55 gallon was a good size for these loaches. I would also like to know if they would be compatiable with the Discus. The biggest one is about 3 in. right now and all three are growing fairly slowly, so I have some time before they need to be moved.
