Newbie has some questions

Hi everyone. I'm Kim from Ontario and my husband Larry and I started
a 26 gallon bow aquarium up with some cichlids. We have 2 dolphins, 2
yellow labs, 2 zebra and 1 I forget the name. They are all swimming
pretty happily around and look beautiful.

We spoke at length to the people at the fish store before we purchased
and did take their advice about water conditions, etc. and followed
that to a letter. We bought the tank from there too so they know what
size we have.

Now, after reading a lot more information I'm getting concerned about
a few things. One - the zebras. I have read that these guys can be
very aggressive. Is this something that will happen as they get older
because they don't appear that way right now. What does 'aggressive'
mean? Are they going to attack the other fish or what? Also - the
spawning. Have to go and double check for the orange on the belly
area to see if one is a female, but I've read these things breed like
crazy. Like hundreds of them in a year. Does this mean we're going
to have tons of these little guys in the tank??? Good heavens, I
can't imagine.

Another question - the number of fish that we have. I have read that
it's more important to have a much long tank rather than a tall one
and ours is 24 long x 18 high. Do you think that as they get older
we're going to have a problem?

Thanks and I'm sorry that I'm so obviously a newbie here but I joined
the list to get some information and learn and I'm willing to take
advice.

Kim and Larry
