OK, I put a bit of Scotch in the glass and I'm ready. I got in this to read what other people wrote but I have a very big, dumb mouth, can't keep it shut, and just have to jump in. (sip sip) So here goes. I just read something I really liked: "I keep the fry with the parents. If they eat the eggs consistently I may raise some artificially but then I look for better parents that care for their young". Why do most of you have fish at all. For me if I can't watch the parents (both of them) guard and herd their young, I do not want them. If I had to artificially mess with the young, I just wouldn't do it. I do not wish to play God. (sip sip) One point here is that if your parents eat the young, you have poor conditions. Experiment. If papa can't get along with mama, you probably should get a bigger tank or guppies. Give the parents better food and conditions and they will stop killing the young and each other. I have read enough to know there are lots of you who agree with me. Not through yet. (sip sip - Neat Glenlivet too) Someone said that the fish would not release hormones or the like to inhibit the growth of their own species. Try to convince a Discus expert of this. The evidence may be anecdotal, but there is enough of it to be pretty convincing. Put big Discus in with small Discus, and long term you will continue to have large Discus and small Discus. Apistos are more than likely similar in this respect. So, even after what I said, eventually you have to get the young away from Mom and Dad. How long do you think they would stay together in nature? Guess that should be your guide. (sip sip) Now if you are still reading I have another one that relates to what I have read today. When I was young (long time ago) I remember a pet store of some fame in suburban Illinois called Black Angel Haven. This guy was pretty inovative and did some breeding on his own. Once he expanded and had much floor space. He put a huge above ground swimming pool in the middle of his shop. At least twenty feet across and four feet deep. He put young Angels, sword tails, and some other fairly peaceful fish in it. He kept it very lightly stocked and fed them well. He also did huge water changes. I went there at least once a week for ages. Those fish grew like you would not believe. Why? From what I have read some of you think you know, but those were the largest fish of their types I have ever seen. Even after he removed them to tanks and sold them they seemed healthier as well as bigger. Any opinions? One more. The harder, and usually more alkaline water for the fry. Think about the environment where our fish live. They generally breed in the rainy season, More rain (checked the Ph and hardness of your rain lately?) more acid and softness. flood the land and pull in the humic acid. Breed in it and the dry season comes. less of that humic acid comming in. Evaporation making the water harder and maybe not so acid. Sound reasonable. The babies have to adapt to it. Maybe after awhile it becomes part of their nature? This cycle of nature explains more things, especially about the "white water" Apistos but you are definitely tired of me by now. What do you think? Must be the Scotch, right? You open it to the public and see what you get. Enough I'll shut up.
