If you guys haven't noticed by my numerous questions...I have a male and female convict 

When I put the male in my 55g it seemed to be chasing only the female convict so the male is in my 10g now.
I noticed that there was a small pit in my 55g, but my used tank came with pebbles for substrate that are about 1/3" and my convict is about 2in" so I thought I just made the pit with my fingers when I was evening the gravel.
Today(after moving my convict to the 10g), I noticed another small pit in my smaller gravel. I had a heater positioned somewhere around there so I assumed the heater made the hole o.o
Now after googling, it seems that the male will chase the female when it wants to breed, and it's not chasing any other fish...so is my male actually trying to get the female to breed?
Also found some thing about a breeding tube when I googled...There's a really small triangular thing sticking out under the female convict. Is that supposed to be the tube?
Edit:I'm going to see if my male convict re-digs the pit in the 10g...tho I'm pretty sure it was because of the heater since there's no female lol
./me is retarded
