We all experience algae at some point in our reefing careers. The usually way to maintain it is by using algae eating fish such as tangs, rabbitfish, foxfaces, snails etc. Now for those people with nano tanks algae is usually is taken care of by snails but sometimes they need a little help when it comes to bryopsis, hair algae, cyano etc.

Well here comes the FW mollies. These fish are usually seen in petco's, petsmart in the freshwater section. These fish actually prefer to live in brackish and some in full on marine environments. They have all the necessary organs to live a healthy lifestyle in our reef tanks. They tend to be voracious algae eaters and eat a wide range of them. They are considerably cheaper than SW fish, and breed regularly.

I have a frag tank that is 24x15x8in and have struggled to find an algae solution. My foxface out grew it in a matter of months and small tangs just don't do well in there. These mollies prefer calmer waters and would be perfect for my frag tank as I have a gyre like effect for flow. I have picked up 8 black mollies, would have preferred the silver ones but nobody had them locally, at 2.99 a pop. This frag tank currently has very little algae due to running mostly blue light(limits algae considerably). This will follow the progression of introducing the mollies and breeding them (found in the sump mostly)! Enjoy the experiment and if a nano tank with algae issue sounds like a problem your having this may be a viable option or if mine breed that is a molly that is fully accustomed to sw environment. Keep in mind no QT is needed if you are getting a molly that has never touched SW as the parasites they may have cannot live in SW. But as soon as they touch SW they will start to build up immunity to SW parasites so you will have to QT the babies if your worried about parasites. I hope to eventually find some Silver, green or ruby SCATS which acclimate to SW life a lot better and are known to eat...Aiptasia :)

Day 1: Slow acclimation minimum of 4 hours. Use airstone and either float bag in tank or use heater for proper temp regulation. I personally put the fish from petsmart water into fresh RODI water with prime and floated in my tank. I will slowly exchange water in the bag with my tank water until proper salinity is reached. If they fish are transitioning well they wil poop a lot which is a good thing. This is showing that they are changing their organs from working in fw environment to saltwater. BE slow. Also when picking out mollies it is best to outnumber the male. I ended up picking up all the black mollies they had to increase my chances of having them survive.

Mollies are in. upon addition one of them ran into my urchin and I had to help him out. Hopeful all these make it through.

Well im already seeing some fails. These fish are VERY weak swimmers. With that they go with the flow but I have an urchin...where they are getting caught in the flow sometimes and getting pierced by the urchin. Unfortunately this may be a quicker experiment than I was hoping

Edit: Cut all flow except for returns. Already lost one from a pierce through the head. Others look a bit rough and out of the 8 I sadly think 3-4 will survive the night. I underestimated how weak of swimmers they were and how deadly flow and an urchin can be.

Fun experiment! Too bad you’ve had some dismal luck so far..

Any update?

I have acclimated Mollies a few times, as well as Silver Tip Sharks... a number of years ago. I had good success with the mollies - but definitely noticed the same thing you did... they aren’t as powerful swimmers. Never experienced them getting stuck on urchins though! Yikes

Unfortunately I did not have any survivors. With the amount of forcethey hit the urchin I had to use tweezers to pull them off. I believe they acclimated fine to the SW but the flow was too much for them to keep control. They were about 1-1.5in so a bit small. The urchin was one thing I never considered to cause death.

Oh no! Sorry to hear that.. Do you intend to try again? Perhaps you could house them in an acclimation box for a few days / week prior to releasing them into the tank. That would not eliminate the Urchin / flow issue, but would ensure they were fully healthy & acclimated prior to getting thrown into tank.. might have no positive affect, but could give them a better chance?

I do not intend to try again. I just feel that these mollies won't fare well in a system this small with the flow long term.
