Mollies !?

Hi! Haven't posted in quite awhile but I've finally got my tropical tank up and running! after having a little trouble with white spot with my marine biOrb I've changed to tropical until I get my bio-cube in the new year. The tank has been cycling for 4 weeks and today I brought home 2 lovely mollies, a black one and an orange one (theres a name for them). I put them in and they seem to be liking everything so far but after some research I heard mollies survive better in brackish water. Will they be Ok in freshwater? and how many can I put in the tank (60l = 16g biOrb) I'm hoping to get 2 African dwarf frogs as well for the tank in a week or two. Would 5-6 mollies, 3 baby guppys and 2 african dwarf frogs be overstocking? (I have the guppies in another tank, there about 3 months old and I want to start the tank again so I'm putting them into my biOrb for the time being.)

Cheers for your help!

I don''t know about those frogs in particular, but most frogs need land. They can't just swim for their whole life.

 

the mollies will be fine they are very adaptable, I have heard they do better in slightly brackish water but they are sold and kept as freshwater fish 99% of the time.

 

Guppies fall in to this category too, along with all other freshwater livebearers.

You should use some freshwater salt for this combination of livestock. The frogs won't mind the salt, and the guppies and mollies need it to do really well.

Also be ready to keep the pH up above 7; none of these guys like it below there. 7.5ish is ideal.

Make sure you have enough room for the frogs to surface; they breathe air, after all.

I don't think it would be overstocked....if it is, it's not by all that much.

 

The African Dwarf Frogs can live in an aquatic enviroment only, but from research I found that the Frogs cannot live in brackish water and I'm wondering know weather to have brackish water and just keep mollies or keep the mollies in fresh water and add frogs, I really want the frogs but I want the mollies to live healthy. Advice?

 

Well, the mollies can do ok in freshwater.....but read on.

I would personally look for another kind of fish, maybe some kind of tetra (since there's a fish for everyone in that gigantonormous family of fish lol), that lives in the same environment as the frogs. By same environment, I mean similar water conditions in terms of pH and salt content. The pH for freshwater fish varies a HUGE amount, anywhere from 4 to 8, but most species won't tolerate that whole range long term.

The frogs like 7-7.8 or so, and 7.5 is ideal, so I would try to find other fish that fit with that if you're dead-set on the frogs.

Likewise, if the mollies are what you really want, I would find other brackish fish, and do a brackish tank.

 

I've kept mollies in freshwater before, If I do decide to keep them in with the frogs will they survive in freshwater?

 

Well, yeah, mollies will survive in freshwater. I was just mentioning that I think we should try to keep our tanks as natural of an environment as possible, rather than throwing together stuff that don't really live in the same kind of environment as each other.
