Help with two issues

[Catica405]

Hi there everybody,

After setting up my new tank and having a very strong tomato survive the conditions of new cycling water, things are going better. Now dealing with a bit of phosphates and a little high salinity, the rest is fine. I am encountering two problems today:

-I added a female for my tomato clown and it worked perfectly the first two weeks, until tonight! Maybe its the first time I see this happen, but the female clown seem to hate my male's guts now. He is very submissive and goes away. What surprises me is that they got along so well for so long, is it possible they don't like each other anymore or can it be that she's not having an awesome day like it happens to human females? ��

-I came home late and when I turned the lights on I saw this creepy creature hovering on my rock and hiding inside a little crack. I read this is a flatworm.. What does that mean for my tank? Is it going to hurt my creatures??
I have two tomatoes, one twin spot goby, one red banded shrimp, two peppermints, one arrowhead crab and hermits cleaning the rock. I also have 4 snails.
(I failed to upload the picture of that thing)

Need a picture to id the critter.

As far as the clowns go Tomato clowns are very aggressive fish, it is what it is.

How big is the tank? How do you know your new clown is a female? How long was the other clown in the tank?

+1 how big is the tank? Tomato clowns need space.

I think I remember the trouble you had in the beginning, glad to hear things settled down a little

Twin spot gobys can be very difficult to keep alive. They aren't great beginner fish.
If your lfs is advising you on this stocking, you should probs not listen to them anymore; if you are just going to the store and buying whatever, you should try to research stuff beforehand more. At the very least you can look fish up on your phone on liveaquaria.com for decent info while you are in the store. Saltwater fish are different from other pets like cats or freshwater fish because they are mostly taken from the wild. That means they are sometimes adapted to very specific conditions that our tanks just don't provide. As opposed to animals that have been domesticated for a few generations.

I believe with the twinspots the issue is that they eat something that most tanks don't have, so they starve to death; but I'm not super sure. The problem with tomatos is they are mean, and need a lot of personal space. That will make it hard to add other fish to "their tank." It's better to figure out everything that will go in the tank and then add them in order of least to most aggressive.

Twinspot gobies eat pods & other micro fauna. So new tanks often don't offer enough to eat.

The twin spot goby is doing great so far. He started eating frozen mysis from the sand too. The tank is a 37g but the thing is that they loved each other at the beginning. Thats why I dont see why she would be chasing him around just now. They have been together for over two weeks.
