Im as impressed with your photography skills as I am the Knife! Without the flash 99% of the pics I take of mine are too blurry to make out what it is and the ones with flash are
well too flashy
Mine is over 5 years old
went from 4~9 in about a year
from 9~12 in about a year
from 12 to 13/14 in over 3 years
I havent put him on a tape measure in several years (he was 12 then) but he is a definitely more then 2/3s of the depth (front to back) of the 125 gal tank he is in
That side of the tank for reference:
Mine has been raised with mid aggressive Cichlids (as docile as Geos, as aggressive as Gold Saums and many species in between) and has never had any issues with them with the exception that the BGK will attack any spawning site in quest of fertilized eggs or fry. Regardless of how tough the Cichlids are
Ive used him to prevent reproduction with several pairs (Geos, Convicts, Dempseys) but his uncontrollable lust for eggs/fry might get him in trouble with tougher tank mates.
Its not too often we see these guys as adults. The lack of examples over 12" makes me wonder why they are so commonly claimed to reach 18~24 in home aquaria
Your looks real nice RD! Congratts.
