Fish War! Please Help Before It Gets Worse.

My tank is at war please help!
Here are my fish and there position in the war.
Team 1 (pre addition)
silver platy (male) : Before the addition of the new fish he was the biggest and has all of a sudden has become terrified and is hiding in the rocks.

lyretail guppy (male) this lyretail guppy is very aggressive and is attacking our new fish avidly.

Team 2 (New fish introduced july 1st 2017.)
red guppy (male) : passive aggressive (will strike when struck.)

yellow guppy (male) : passive aggressive (will strike when struck.)

cremecicle lyretail balloon molly (male) : Highly passive, he just swims around even though he is harassed constantly by the lyretail guppy.

I have a 10 gallon tank.

Also I have small algae growth on the edge of the tank, we cleaned most of it but there is a little left is
this a big problem?

 

There is just not enough room for those fish in a ten gallon tank. That's part of the problem.

 

Welcome to fishlore

I agree, it is most likely because you are overstocked

 

I talked to the people at the store and they said it was fine and I was in fact under stocked. my fish length total is about 6 in

 

Inch per gallon is inaccurate and your supposed to stock by size, bio-load, and temperament. Saying 1 inch per gallon is true is like saying a 30 inch Arowana could live in a 30 gallon tank. I would either get rid of the Molly and Platy and keep the Guppies or get rid of the Molly and Guppies and keep the Platy and get 2 more Platies.

 

here are some pics of the tank.

 

The molly needs a bigger tank. In a 10 gallon you could do 3 guppies or 2-3 platies and preferably females which wouldn't fight in such small groups.

 

Any suggestions for before I purchase the bigger tank?

 

Add some more hiding spots and things to break up the lines of sight.

What temperature is the tank currently?

 

I would get a 20 gallon personally. I own 2 (one long and one high) and really enjoy them. I would get whichever one you like (consider the size of the furniture you want to put it on and how much weight it can hold). Once you get a new tank, you'll need a larger filter. You can use the same filter bag you have right now (since I assume the tank is cycled) and put it in with the new one (place it right behind it, I assume it's a hang on back style) and let it run like that for several weeks so the bacteria colony can grow on the new filter bag. You might consider getting equipment that is rated for a 20 gallon (air pump, heater) or even a 30 gallon rating.

I wouldn't worry about fish stocking at this point. Just get the new tank up and slowly add the fish. Make sure there's plenty of cover to break up line of sight.

 

Any suggestions for before I purchase the bigger tank?

I would reccomend getting at least a 20G tank.

 

The petco dollar per gallon sale is july9-august19. Great time to upgrade

 

The all male strategy is flawed, but get a big tank while they are cheap.

The biggest part of your problem is space . You need a larger tank , I would suggest a 30 gal . You need to have many places to hide , vegetation , rock and driftwood . When you or if you do this the quickest way to set it up is put you fish into a bucket and then use the water from your existing tank (10g) into the 20 or 30 gallon then fill the rest with live water and your tank is ready and cycled assuming you 10 g is completely cycled .

 

I had male Lyre Tail Guppies a few years ago. Man, they were mean!
Beautiful fish but geez. I watched a several of them go after another lyre tail and took him right down. Just bullied him to the gravel. I had to intervene.
Mine were in a 30g. I don't know if they're all like that.

 

thank you all I am planning on upgrading very soon.
any suggestions as of what to do with my ten gallon?

 

problem..
I come home to as far as I can tell is a battle for dominance of the tank between the lyretail guppy and the balloon lyretail molly.
it appears that the red and yellow guppys have given in to the lyretail guppy and the red one has a nick in its tail fin.
also when I turned the light off the all calmed down and stopped fighting.

 

I talked to the people at the store and they said it was fine and I was in fact under stocked. my fish length total is about 6 in

Don't always trust the store employees, most of them don't actually know their stuff. It could just be natural conflict between the fish.

I would set it up for a single male betta. But that's just me. Good luck!

 

maybe you should keep the lights off more until you get a bigger tank... that would help reduce your algae as well.

We scrubbed some of the algae but the fish seem to love to eat it.

Odd. My lyre tail guppy in my home tank is the most peaceful of the three guppies in my home tank. And I don't get to see the guppies in the office tank I take care of very much (I only get to be there about 3 hours per day at the most and a lot of that time is spent doing API tests or water changes), but one is a lyre tail and I haven't seen any fish fights yet.

 

For a stock for a empty 10 gallon if you upgrade I would do(and am doing with my 10 gallon):
8 Dwarf Pencilfish
2 Scarlet Badis
Cherry + Amano Shrimp
Assassin Snail

 

You could keep the 10 gallon as a quarantine tank! Let new fish hang out for a week or so there to make sure they're healthy. Then add them to your normal tank!

Using it as a QT is a great idea! However you want to keep your new fish in quarantine longer than a week to be sure they're not sick

LOL I have to say I love your profile picture of your catfish. I have 8 cats and that's why all of my tanks have covers.

 

It also doesn't help they're all male either! 20 gallons tanks are really cheap, it'll give them more space to relax and establish their own spots in the tank

For finding tanks, use apps such as OfferUp, LetGo, and Craigslist! Good luck, and be sure to update us on what's going on

Just wanted to mention this - putting your old water into your new aquarium will not instantly cycle your new tank. The beneficial bacteria doesn't live in the water itself, it lives in the filter media. So to cycle your new tank you need to run both the old filter and new filter in the new tank for a few weeks. Assuming your current tank is cycled, of course.
