If I had your setup I would as there's plenty of space for it. Like @eatbreakfast said they're not going to add much to your bio load, but it will add an element that most fish can't. When my friends stop by they look at my fish but love my eel.In your opinion do you think that I would have room for the dwarf moray with the stock that I have now? The moray would be the last thing added. My tank has been up for over 6 months now.
