I will preface this post, I am a complete newb who is keen to learn and I spending a lot of time understanding how to manage and grow a good community of fish. Eventually I want to have a marine tank (would be a new tank of course!), but I feel this is the first logical step in the knowledge progression.
I have recently been setting up a new 5ft tank that has been cycled and I have started to build up the community. This is a tank that isn't just for my appreciation but my entire family. My 3 boys, wife and I have really come to enjoy our small gold & catfish tank so much so we went and added this second one. We quite enjoy the more colorful varieties of freshwater. I have become quite fond (and so has my family) of the Kribensis Cichlid from seeing them in a local fish store and pictures. I have been doing quite a bit of research about them so I have some questions about making this tank work with them.
But first I will endeavor to give some background on current status of the tank.
Currently we have the following fish & Filtering
3x Albino Corydora's
2x Albino bristlenoses
1x Eheim 2217 canister filter (1000l/ph)
1x SunSun 2000l/ph canister filter (backup)
1x AquaOne 990 AirPump
At least 8 different ornaments & places which would be considered a place for the Kribs to hide, potentially adding some more to create a layered tank so the bottom dwellers (kribs & catfish) can have their space and territories (Kribs), Some ornaments will be quite tall to allow the upper layers to have areas to swim through, including taller fake plants. No live plants, lots of fake plastic plants and want to avoid getting live plants for the moment at least.
I am looking to add more dither type fish over the next two weeks in order to prepare for the arrival of the Kribs which my local pet store says would arrive in around 3 weeks time. The plan is to add this week another 6 Platy's (exactly a week after adding the last 3, plus 1 bristlenose). Then next week 6 danios or Tetras. From my understanding the Kribs and other fish do well with having these higher level dither fish.
1. Would I be able to add in 6 Kribs, and if so what should be the sex ratio.
2. My eldest son really likes the cloan loaches, would I be able to add one or 2 of them, from what I have read due to the size they grow they don't seem to bothered by the kribs protectivness when they lay eggs. I think it is just the corydora's which I will have to sell or give away because they may have a problem.
3. After the Kribs, I would like to add another batch of community fish either guppies or more tetra's, would this be too many fish?
Thanks in advance for any advice and help, apologies for the length of the post and if I have failed to provide any important information.
