I'm afraid to say I'm pretty new to betta keeping, so if this is a newbie question, I apologize.
I just got a little double-tail male about three weeks ago, and I've been experimenting with the setup in his tank. I was worried at first that I had too many plants in there, but when I took one out last week, he got so stressed out that stripes appeared (stress stripes, I think?) and he refused to eat.
When I put it back in, he was completely happy again, and even started building a bubble nest around the replaced plant. It was the only thing that had changed in the tank, so I assume he must just like a busy tank.
However, with the addition of a new "moon rock" cave, I'm again concerned that it may be too crowded in his little 2 gallon tank.
Below is an image of his tank setup at the moment.
What do you think? Is it possible to have a tank too crowded? Does he need more room to stretch?
He doesn't seem stressed or anything with this set up, but I just wanted to make sure it wouldn't cause problems for him!
