new to this site... visited many times the past month. but i just got around to becoming a member. first off i have a 20gal with one dwarf gourami,1 killie,4black tetras,and 7neons. my 10gal has a electric blue cray only about 2" at the moment. i was wondering if anyone would know where to get a orange (dwarf mexican) crayfish for my 20gal or if it would even fit with what i have in it already. ive been having trouble getting any info so any feedback would b helpful.
