Molly Fry Rapidly Dying Help!

[sami the cichlid]

Well, i bought 3 pregnant females on the weekend, 2 gave birth on sunday. The black molly had only 8 babies in the morn and the multicolured molly had 20.
I put them in a seperate 2 gallon tank with no filter. on tue and wed 3 babies died altogether (only the multicoloured mothers babies) so i added a filter (fluval U1).
The next day (2day) i found 4 dead babies (all multicoloured mother again) so i thought the filter pressure/current was too high fo a small tank, so i moved them into a larger tank. During the move 12 multicoloured babies died!
i think it was the stress of the move. oddly, NO black molly fry have died!!!!! and i also have another prego molly and dont want a repeat of the last 4 days.
Any advice welcome

I don't know much, but I had two dalmation Mollys and two black mollies and the black ones were definitely 'hardier.' Perhaps that is why. SOrry you lost them.

Welcome to the forum Sami.
If you are putting the fish into new tanks with no heater or filter, you are not giving the fry much of a chance. Even a newly set up container can work if you can keep the temperature about right and can provide clean water each day to replace the poor water quality that will quickly develop. All new water needs to be treated to remove chlorine and chloramine or else the chemicals themselves will kill the fish directly. I use Seachem Prime for that purpose but there are lots of good dechlorinators made by several different companies. Another factor, peculiar to mollies, is that the fish really do not do well in soft water. My tap water is quite hard and mollies do great in my tanks but I know people who have much better water that have trouble keeping mollies alive.
