So we FINALLY have everything we need for our 55G tank. All we need is to put the water and gravel in it. We however are still considering what fish to put in it. We would love to put a Banjo Catfish in it, but we read that gravel is not recommended for it, due to the fact that it will scratch it up and that it loves to burrow in the sand like a ray, but cannot with gravel. Are we able to get one, or would it be cruel punishment to have it with gravel? Thanks guys
