Hi everyone. Sorry, this is going to be a long post, I just want to know how to take care of my Petricola. They are simply too awesome.
I have 3 Synodontis petricola in my 55 gallon right now. I have had them for about 2 months now. They are sharing the tank with a couple species of Central American cichlids, a shoal of Tiger Barbs, and a Bristlenose pleco. Everyone gets along, I think the cichlids could care less about the petricola.
I feed them at night, however, I rarely see them eat. I drop lots of shrimp pellets for them, along with a couple algae wafers (they share with the pleco, so I usually do two wafers)
One is full-grown, or at least it seems. He is 3 inches or so long, and the other two are about 1.5-2 inches long.
They almost always hiding in their rock pile. I can see them in the rock pile, they are not stationary, they are certainly active in the caves, but they don't seem to want to come out. They seem almost afraid of me haha, when they see me, they dart for their caves. Everything I have read, seen (At the LFS), and been told that is these little guys are fairly active during the day, but it doesn't seem that way for me.
They are a shoaling species in the wild, so I can imagine it is possible they are not feeling secure in such limited numbers.
I was offered 1" petricola for $5. I may take the deal.
Here are my questions-
1. Would adding three more petricola give them more security? As a shoaling species, it seems that the more, the merrier. I don't know how the different sizes will add up though, considering I have two 1.5" specimens, the large 3", and the soon-to-be 1". Would the size matter for them?
2. Am I giving them a proper diet? They get shrimp pellets, algae wafers, and it seems they clean up all the brine shrimp from what's leftover when I give my cichlids their weekly treat. They don't obliviously get any flake food or pellet, the cichlids don't let that get to the bottom, haha
3. Is there anything special I need to know about this species?
Thanks so much guys.
