I am using a pair of black mollies to cycle my marine tank. They need to be acclimated slowly but do very well - no problems with parasites (white spot) in the slat water! I thought the female was a little too shy at first but she was merely finding a place to drop some babies. They love the marine macro algae (caulerpa).

I bought two of these beautiful fish and after three weeks they had developed white-spots on fins, body and eye. Adding Sea-salt to the aquarium cured this problem within a week and restored them to there natural charm.

I love the look of the fish, but there can be problems! I bought 3, they had little lucky (baby), but brought whitespot, same thing happened with my dads when he was a kid. So I would think before buyin em!

From: David
I have had disease problems initially every time I've tried this species. A sea salt bath helps and once over it they do quite well kept among livebearers with a little salt in the tank unfortunately a lot of salt can hurt your plants which they like as well so you have to find a balance.

I have a 30 gallon tank full of 5 different kinds of mollies,they are all breeding with each other so I hope to come up with an unusual color of molly. I love my molly tank and find it very interesting to watch

From: Zane
Mollies are shy fish, easily stressed in a bare pet store tank. Initially they often suffer from fungus or ick. Once placed in a well-planted aquarium, they are hardy sociable fish and worth the patience.

From: Matt
I have 25 baby mollies now. So far their mother hasn't eaten them yet. They are growing very fast.

I love my mollies! they get along great in my well planted 55 gal tank with the platies. I have 2 white females and a Dalmatian lyretail with coloring similar to the one in the picture here like brownish but not like those chocolate chip ones with the red eyes. Mine has regular colored eyes. mollies are beautiful fish!

From: Susan
I just love these characters, Larry, Curly,& Mo, and boy do they fit their names. They are so human friendly, they greet me each and every time I go to the tank ( I know its for the food) but that's OK, I'll think what I like. PS I also have sailfin & Balloon mollys, extremely cute but not as goofy as Dalmatians. p.s. I love your site...

From: Beverly
At last! After almost 2 years of struggle, research, and heartbreak I think I have finally learned the secret of successfully caring for this wonderful,funny,engaging fish species. There is no fish as enjoyable as mollies, when they are healthy, they are so much fun to watch, and when my husband firmly denied me a fifth tank that I requested because of my overpopulation problem, I knew I had arrived!!

From: Nan
Very important: mollies will not do well unless you add some salt to the water.

From: Kelly
I have two black balloon mollies which are not mentioned in the above, and they are so adorable! They are also little pigs, might I add. They eat absolutely *everything!* It's good fun to watch them eat because they try to get so much food in their mouths at one time they don't know what to do with it!!

From: Amy
I bought one black molly, and soon had another. I raised this one, and 6 months later I had 20 more. Now every 2 months I get 40 or so more! The cycle never ends. They are a peaceful fish, but they sure do have a lot of babies!

From: Andy
I bought 4 balloon mollys and after a time they bred. They can give birth every 30 days. Expecting more balloon mollys I found I had green mollys,silver mollys,black mollys spotted mollys all shapes and sizes. They don't eat their own and they are never ending. Now I had to start several tanks to accommodate them all,and now I still maybe over crowded in 1 tank at least. So I say be careful with these mollys they go on and on and on.
