I just recently got my first tank up (20 gal) with 3 cichlids and a pleco. I was wondering if you guys would be able to identify these 2 fish...couldnt get a pic of the 3rd cuz it hides...and also the bigger 1 thats hiding just recently started pulling out gravel from under this little log and stacking all the gravel in 1 spot so im not exactly sure what thats all about...if you guys could fill me in id appreciate it.
