I have what i think is a wyckii. Its that, a red tail or a numerus but is albino so hard to tell. It has a long tail streamer which the others dont have so i think its wyckii. He is about 8" maybe 10" and is fairly active. Ide say he swims around 25-50% of the time unless he has a stuffed stomach. Tank is dimly lit though and has lots of driftwood in it.
Isnt half as agressive as what i thought either although i guess hes not that big yet. At the moment he lives with a 10- 12" Jardini (i suck with sizes), an ornate pictus and another few small things in a 180 and they have the occasional fight but no skinning fish alive like i have read. He def doesnt back down though when challenged.
