Started a 55 gallon 2 and a half weeks ago. The tank is cycled from have a established filter transfered to it and also planted very heavily. I have 22 serpae tetras and only 5 peppered corys at the moment. Plan on getting at least 5-7 more. The 5 corys have been in there for a week and seem to hide in/under my driftwood while lights are on, only coming out a little. Now I knew it was risky with the serpaes but after doing a lot of research the consensus was that if I have a big enough tank and enough of them they would keep the nipping to themselves. It seems when the corys do come out their will be 2-3 tetras that seem interested in them and eventually give them a little nudge but not nip. Are they scaring the corys? Do you think once I add the remaing corys they will become a little more brave?
I will add that once the lights go off they do come out and will eat their food. Another question is that they stay on bottom probably 95% of time. Is this common with this specie, as my albinos are all over in my other 55 gallon. The albinos settled almost immediately also. Could this be an adjustment period , lack of numbers or are the serpaes an issue? Any help would be appreciated.
