first off it makes a lot of sense to breed cichlids for feeders because most of the fish i keep eat cichlids along with other fish in the wild,my goby who are myyfavorite fish love live food and pet store feeders arent that healty or nutritional. i like most people started out with cichlids over 20 years ago and grew away from them to the person who said breed convicts what is a 14 inch fish that can eat its own wieght in food a day going to do with convicts nothing. i keep cichlids that have large spawns and grow fast to keep my fish healthy also i raise most all these cichlids from babys so i know they are full of all the good stuff i gave them to eat. another thing is you people claim to know so much but just prove you dont and are repeating what you heard, how many of you posting right now has 2 pair of dovii that have been and still can be breed in tanks from 10-75 gallons without fighting or eating the babys ,i also have a grade a show quality pair of black nastys that i have been offered lots of money for, a breeding pair of cubans that are out of this world and a few smaller cichlids like loseli and firemouths. the thing i like about cichlids is breeding time the interation and courtship is amazing and the breeding colors and thats about it for me with cichlids ,the thing is when goby breed cause yes i have had breeding pairs of gobys to the male always beats up and almost kills the mom and they dont raise the fry together that the bad part. also people like to belive that dovii umbees and jags swim around all day in open water chasing food only in small ponds and creeks in the big water they are trying there best not to become dinner for a lot of true predators. tanks requirents are fact they are guesses minimum tank sise for a marbled sleeper goby is 100 gal but my big male is in a 125 now and he will need bigger in a year or so, another thing is dovii dont grow like these people are thrying to say they grow to between 12 and maybe 16 inches in the first couple years of life and then growth slows to maybe a inch or 2 a year after that. just like the pic you posted saying this is how big dovii get duh and i bet that fish is about 6 to 9 years old. also im not some dumb kid who just got fish when mfk came along and i know a lot of stuff you guys pass around on this board is bs you overheard not actualy experience for not what youve heard or what your boy said or the guy on the board how many dovii have you had (you had) that outgrew a 140 gal. so save all you bs for someone who wants to hear it. p.s my big male MARBLED SLEEPER GOBYloves ciclids
