So, does anyone on here know anything about fish? I bought some fish today at Uncle Bill's pet store. One of which was a pregnant dalmation molly. I have never had a pregnant fish before. Do I need to sepearate her? I was talking to my grandma today and she was saying that she thinks most fish try and eat there babies. I was surprised, I mean that they don't take care of them. I thought that they would at least show them where food is and stuff, but I guess not lol. I mean at least broodies try and point there, usually non biological chicks, in the right directions. I guess in some aspects chickens have ruined my view on other things lol.
Also I never really thought about this until now, but I hope there aren't any permits or laws pertaining to swap meets that I am not aware of. I am off to research
Almost all livebearing fish do not take care of their young. Some are more aggressive than others about eating their young. All the advice you've been given about providing cover is spot on.
What size is your tank and who all lives in it (number and species)? Bushy and/or grassy plants are great fry cover. If you have plastic plants you can even just "unplant" a few and let them float at the surface to provide that level of cover. If you really want some survivors, though, a breeding setup may be the way to go - but you'll have to really stay on top of keeping the water clean (mollies are among the more sensitive of the livebearers). .....or you can keep an eye on your female and when she starts dropping fry just remove a few and put them in a "safe" place for the first couple of weeks. Molly fry tend to be pretty good sized at "birth", so it doesn't take too long to get them to the less tempting size.
Different species of fish are different about the whole reproduction thing. Livebearers are very canibalisitc as a group. Egg scattering species (those that just kind of swim around scattering eggs and sperm and swimming off) are also pretty prone to eating both the eggs and the fry that hatch. There are,j though, several species that provide a range of parental care -- from guarding the eggs to secreting a nutritious "slime" from their body for the fry to feed off of, etc. If you want to see some great fish parenting, cichlids are the go to group..... we have a pair of angels in the spawning tank now (I use a spawning tank for them because their community tank also houses a 12 inch pleco who is quite fond of caviar - no clutch stands a chance of making it through one night with him in there) that will literally come out of the water at my hand when I reach over to feed or do any maintenance. My DD's breeding group of plecos have been fun to watch too - they are in the group where mom lays eggs and splits but dad provides the best care by guarding and fanning the eggs and then providing security for the kids for the first few days as they find their fins.
55 gal. I have some fake plants coming in the mail. In this tank there are 6 mollies, 1 calico fan tail goldfish, 1 angel fish, 2 of those black bug eyed goldfish I can't remember the name of, and a scum sucker.I have raised cichlids. I used to keep oscar fish but wanted to go with more of a community tank this go around.
Almost all the fish you listed will try to eat the fry. So the more cover the better. The plant I have found that is the best for cover is Java Moss. It thrives in lower light situations, and provides lots of cover for fry. You can tie it to a rock to keep it near the bottom, or just let it float around.
