Overstocking SAcichlid as juveniles

  • We are currently upgrading MFK. thanks! -neo
Yeah I was afraid of that for the Salvini. She was nasty when I added the geos and I got them about a week or two apart. She was 1.5" then. She was mostly nasty towards my red hump and for a bizarre reason a few days before I removed them, she suddenly became buddies with the geo and wouldn't leave it's side. I know my fish, but I'm still scratching my head on that one. I removed the geos regardless because I had already made up my mind that they needed to go.

Originally when this all went down I had 1 1/2" Salvini, 2 small geos, 1/2" ebjd, 2 tiny kribensis, sailfin pleco, 1/2" bush fish, 1 reedfish. She had a vendetta for that geo the moment it's bag was put in the tank, I had never seen her colors change before then. I had I think two or three more batches of fish come into the tank after quarantines and she didn't mind any of them. I saw maybe a nipped fin or two, but they were the type that healed in a day or two. After the arow had gone through QT and was put into the tank, it was pretty freaked out. All the fish hovered it for the first day and she took a lot of interest in it. She wasn't exactly relentless towards it, but she nipped a few times and it was too afraid to eat with her around. Since it was pretty darn skinny when I had first gotten it, I decided to remove her until it was a little bigger and more adjusted. None of the fish have looked at it since the first day. I'm unsure if she's necessarily snapped, but I've hesitated adding her until we've allowed whatever we decide on to grow.

I've taken her out of the factor of my tank, at least for the time being, but the trial and error is kind of the way I'd like to do things. I've just had more success with this method than adding things that look good on paper together. I've got a hospital tank (not the one the salvini is currently in) ready in case I ever need it as well as a relationship with my LFS who will take anything for me.

And as Duanes said, they are best grown up together as juvies and since I'm still mixing and matching with trial and error, I've debated on overstocking a group of juvies so I could remove them without worrying about having to add a new juvie in it's place into an established tank. When I mean overstocking, I don't mean overstocking when added, I meant it would be overstocked if kept that way. Not sure if that would make much of a difference. I mostly just wanted to know what people think would be a reasonable number of baby fish I could add taking into account that as they grew things would be removed. I kind of had an idea, but sometimes it's nice to bounce ideas off of people.

It's interesting about the territory though. I hadn't really ever thought to approach things in that manner. I knew african did best with less territory and overstocking so there would be nothing to claim, but could that really curb aggression? I haven't really noticed anything too aggressive in my tank, just the jewel starting to fin nip. It wasn't out of control, but I could tell it was just the fish's personality.
 
I do a rearrange of the tank once a month when I take the opportunity to get a good vacuuming in the nooks and crannies I usually can't reach with decorations in my weekly W/Cs. Like I do a "spring cleaning" and we clean the tubes of the canisters and I clean the lids and glass cover (so algae doesn't grow where our air stone is) etc. Do you guys think that's a bad idea? I realize rearranging can sometimes make the fish have to squabble to re-stake a territory, but so far it's been fine.
 
Here's our tank. Excuse the poor quality photos. The combo of a crappy light (being replaced soon) and a crappy phone makes it hard to see anything.

this is the current layout. 4 different types of driftwood, all hollow one floating. There are a few plants behind the large driftwood on the left and floating driftwood above that can't be seen with the poor picture quality. We plan to move the little cave in the middle and we're building a large cave for one of the corners. We just bought 4 lbs of river rock from lowes yesterday and did the vinegar test on all of them. Half made it so we're building a cave tonight then letting it cure for a few days to a week

Already looks like your dogfish have outgrown the tank ...
 
Nice tank.

I've debated on overstocking a group of juvies so I could remove them without worrying about having to add a new juvie in it's place into an established tank. When I mean overstocking, I don't mean overstocking when added, I meant it would be overstocked if kept that way.
I've done that quite often, grow up a mess of fry or juvies that will obviously need to be progressively pared down with time. Nice thing about that is you can select the keepers from the group, whether in terms of color, size, temperament, etc., and sell or trade the others (assuming a market for the particular fish).

How many to put in a 125 just depends on type of fish and their size. You could potentially put quite a few, but good idea to consider species, temperament, their ultimate size, how fast they grow, etc. For example, how many oscars (fast growing) and how many geos (slower growing) to stock would be two different things.
