New to having a fish community

We just set up our 150 gallon tank 2 months ago with a lovely community of fish...2 dalmation mollys, 2 sword tails, 6 glow fish, 6 guppies, 2 gouramis, 4 tigers, 4 Cory cats, 3 snails, and 2 clown loaches. Does this sound reasonable or too much? They all are so 'happy' and so fun to watch. I feed them 1 to 3 times a day--flake food. How often and how much water change should I do? I don't want to clean the tank too much or not enough. I have only had Oscars in the past and 2 at the most in this 150 gallon tank. Sorry so many questions. I really like this forum. Tx

 

I am far from an expert but as far as the fish you have I think you're stock amount is fine. Maybe even under stocked. That's not to say that some people won't chime in with some compatibility issues. That I can't really say. Good luck!

 

Welcome to fishlore!
What type of gouramis?
Clown loaches need a group of 6+ as they are a schooling fish.
Cories need groups of 6+ of their own species, not mix and match.
4 tigers? You mean tiger barbs? They need groups of 6+ but a group of 10-15 would be better as they'd be less nippy.
What type of glofish? Are they glofish tetras, or danios? Or both?
The tiger barbs in that small of a group will attack the gouramis and the livebearers.

 

HellO! Welcome to the forum,

+1 to what Anders said. All of the schooling fish will need at least 6 (ideally more). As far as water changes go, different people do different things. Some always change 20 or 50%, others (like myself) change different amounts each week. I base the amount I change on water readings. For example, if my nitrates are at 20, I would probably change 25%. If they are up to 40, I do a 50%. Do you have an API liquid test for ammonia, nitrites, and nitrates? I

 

There is nothing wrong with housing those breeds together as far as I know, but I do know that Tiger Barbs are listed as semi-aggressive and are fin nippers. They might be fine with those other fish though in a tank that big as long as there are plenty of hiding places.

 

+1 to Anders.

Depending on what type of Gourami's you have, you could have issues. Gourami's are the same suborder as Betta's - Anabantoidei. And we all know what happens when you put two Bettas together.

 

You may want to see what sex the mollies are. If they are not the same sex then get more females. The males are known for breeding the females to death. I just had to re-home a male for that. Plus they are live bearers ... and breed faster than bunnies.
