Starve mollies to get rid of hair algae

8 Mar

I’ve got hair algae in some tanks.  It’s hard to get rid of. I had heard that Mollies will eat it, if they are hungry enough.

So, I gave it a try. A pair of  Black Mollies in a planted tank. No food. After a few days I saw the Mollies eating algae. I got my hopes up. I saw piles of green poo at the bottom of the tank. But, after a few weeks the algae was looking as strong as ever. I started feeding the Mollies just out of sympathy. I fed them a small quantity  and only once a day.

See the green squiggly stuff below the fish?

I pulled the algae out by hand. The aquatic plants (Ludwegia and Rotala) began to take over and now the plants dominate. The algae is still there, but not much.

Much better!

My conclusion is that the Mollies won’t solve a hair algae problem, but they can help, in combination with hand removal and other live plants that use up the nutrients.

Most Colorful Fish contest. Saltwater versus Freshwater.

10 Jan

Freshwater fishkeepers often say “Someday I will set up a saltwater tank. They are so much prettier.” Are they right?
Let’s have a contest. I will be the judge. Are saltwater fish more colorful than freshwater?
I’ll rate the fish from 1 to 5. Five is the best score, the prettiest a fish can be.

Let’s start with a red fish:

Freshwater fish, the Red Velvet Swordtail.
velvetredsword

I’ll give the Red Sword 5 points.

The saltwater red fish, the Coris Wrasse:
corisredjuv
I will give the Coris Wrasse 4 points so the score is Freshwater 5, Saltwater 4.
Wait a minute, the Wrasse grows up and loses his red color!
RedCorisadult
A beautiful fish but not red! I give it 2 points. The score is Freshwater 5, Salt 2.

Let’s look at a White fish:
The freshwater entry is the albino Corydoras Catfish.
albinocory
This catfish does not look like this in the natural state. Albinos do not survive long in nature. I’ll give it 3 points.
I can’t think of a white Saltwater fish. Zero points for the Salties!
The score now. Freshwater 8. Saltwater 2.
How about a yellow fish?
Here’s the freshwater Gold Barb.
gold-barb
Not bad. I would say 2 points for them.
Here’s the saltwater yellow fish, the Yellow Tang.
yellowtang
Wow, that’s a FIVE for sure. That makes the score 10 to 7 for the Freshies.

Oh, wait a second, there is a last-second entry for the freshwater team!
The Electric Yellow Labidochromis. An African Cichlid.
yellowlab
That’s worth four points at least. The score is getting wider.
It’s Freshwater 12. Saltwater 7.
On to Blue.
Freshwater has Blue Platies and Blue Gouramis but the bluest is the Electric Blue African Cichlid.
electic_blue
I’ll give it two points because the female is not very Blue. (sorry, ladies)

bluefemale
Here’s a saltwater Blue Damsel.
bluedamsel
That’s an easy 5 points for the Salt team.
The score is now Fresh 14, Salt 12.
Green fish are the next category. I thought there would be more green fish. They could hide among plants. From an evolutionary standpoint I think green would be a good color to be.
Here’s a freshwater green fish.
Electric Green Tetra
That looks like 4 points.
And, in the ocean, here is the Green Chromis.
green Chromis
I’ll give the Chromis 2 points.
The score is now Freshwater 18. Salt 14.
Hang on! Time-out! A penalty has been assessed against the freshwater team. The Green Tetra is  a genetically modified fish. Cheater!!!!4 points are taken from the Freshies.
The score is now tied 14-14.
Let’s look at Orange fish.
The Sunset Platy.
sunsetplaty
I like these Platies and give them 3 points for orangeness.
Here’s a saltwater Flame Angelfish.
flame angelfish
Almost all orange except the stripes. That’s a beautiful fish worth 4 points to the Saltwater team.
The Salties pull ahead 18-17!!!
Black fish are next.
Here’s the Black Molly in a tank with a black background.
blk
Here’s another Black Molly.
black_molly
That’s the blackest fish in the world. 5 points for the freshwaters.
The saltwater entry is the Domino Damsel.
dominojuvi
That’s four points for the salt. The score is tied 22-22.. oh wait here’s an adult Domino Damsel.
dominoadult
The damsel only gets 2 points.
Freshies are back on top 22-20.
The last category is multi-colored fish.
Here is a group of Discus.
discus
Since these are all modified by captive breeding I’ll give them 3 points.
Freshwater 25-20.
The final entry for saltwater is the Mandarin fish.
Mandarin-Fish
Fantastic, that’s five points!!! I wish I could give it a ten.
The score is TIED 25-25!!!
How can I break this tie??
How about the ugliest fish??
Freshwater?
freshtoadfish
4 points?
Saltwater.
salttoadfish
That is just as ugly. 4 points for the Salt team.
Still 29-29.
OK, one last chance to solve this issue.
I decided to do a Google Image search.
Freshwater fish.

googlefresh

…and the Google Image search for Saltwater fish.

googlesaltwater

And the winner is …… Saltwater … by one point.
I’ll admit the saltwater fish are more colorful, but just barely. If you have a freshwater tank don’t be jealous.
97.5% of the Earth’s water is saltwater. 0.3% of the water is in freshwater lakes and rivers. The rest is groundwater, snow, and glaciers.

Mollies and Salt

3 Jan

Another reminder about Mollies. They do well with salt added to their water. It would be best to make their tank a brackish water tank, maybe one-fourth as salty as a marine aquarium but that can cause other difficulties. Plants don’t do as well in brackish water and you are also very limited to other fish that like brackish water.

To make it simple I keep my Mollies, both Silver and Black, in a tank full of Hornwort and Java Moss (and Duckweed and Water Lettuce on the surface).
I add a LITTLE salt.
How much?
I don’t know. Not much.
How much is that?
Umm…maybe a tablespoon per ten gallons.

Over time the tank will get less salty because of water changes. I occasionally add more salt.
How much?
I don’t know. Not…
Don’t start that again!

A little salt and the plants are fine, the Mollies are incredibly active and disease-free. They live with some Endlers Livebearers (OK, Guppies!). Other good tankmates are the Platies and Swordtails.
Don’t use table salt. Use salt made for marine aquariums or the salt labeled Aquarium Salt. Don’t keep your mollies in soft water, they prefer hard water with a relatively high pH, like the African Cichlids.
