Mollys; IMPORTANT!

Question
Okay, I am buying three Mollies today. A female and male Dalmation, and a female Black. I am also buying a suckerfish of some sort. I am looking to breed. Right now I have a tank with rocks and a filter/pump. If I buy some plastic plants and put them in the corner will the fry be safe? What would happen if I just let a plastic plant float on the surface? Would the fry be safe there? As for feeding, How often do I feed the adults, and how often do I feed the fry? (they'll be in the same tank, so how do I go about that?) and If I rub tropical fish flakes between my fingers until it's fine, will that be okay for the fry? Also, how much do I feed the adults/fry? I'm sorry for all the questions. I just need to know before we go to the store tonight. and I can't buy special food for the fry, or a breeding tank, so plants/rocks are going to be the only hiding place right now.

Please help,
Emphasy

Answer
The best thing you can do is buy a small breeder net/container that you can keep the fry in, these usually will float in the water in the tank you already have established. Other than that it will be very difficult to ensure the fry are getting proper nutrition, until they are big enough to make do on their own.  They can easily eat crushed up fish flakes.  Once they near normal size that they can eat on their own things should run smoothly it sounds like they have places to hide.

Feeding the fish, I feed mine every other day and they do fine. In the wild it takes them sometimes days to obtain the nutrients that flakes give them so they do very very well now that all the vitamins and things they need can be found in one flake, you should feed the babies daily. No more than they (babies and adults) can eat with in 15 minutes. There stomach is about the size of their eyeball, over feeding can get really bad.

Before you get a sucker fish, do you have any algae growth in your tank at the moment? What size tank? (as most Plecostomous require 55-75 gallon tanks by the time they are full grown)  

Chinese algae eaters stop eating algae and will turn aggressive on other fish. One I can suggest is an Otocinclus Catfish these guys stay small and do wonders cleaning algae from the glass! I hope this helps!
