Keep an eye on the situation. They might sort out the pecking order. Shuu, my regular Dwarf, sometimes chases Oko, my neon blue, around the tank but it never goes further than that. Most of the time they hang out and eat together with no issues.
Is your tank well-planted? If not, consider doing it. You can use fake plants if you're not keen on the real thing, just as long as you give them plenty of variety and have a lot in there. For one thing, the blue looks gorgeous shimmering in and out of the plantlife, but most importantly it gives them privacy and places to hide if they want to escape each other.
Don't wait for it to escalate to biting, but if you see it happening more consider rehoming him and getting a female or finding another species that is compatible.
