I have a HUGE white cray named ESCOBAR...he's about 5" plus and I also have a small orange(ish) cray who is under an inch in a 55 gallon...Pepe', the smaller one, hides alot...so far all seems well...but I didn't plan on this...an online order threw me a curve...sending the HUGE white one contrast to the orange...online fish ordering...its a gamble.
