some fish would help lol jk!!
what kind of fish do YOU want and how big is the tank?

lol i have fish, theres a red zebra a kenyi and a livingston but i dont know if im keeping the livingston cause i just found out how big they get. The tank is a 90gal. What would you sugest?

a livingstoni will be fine in a 90g. they aren't very aggressive when they have a lot of space. if you've got those cichlids in there now, I would recommend you find some young peacock cichlids, they come in all different colors.

Is the Kenyi yellow or blue? Males are yellow and have a very nasty habbit of nipping other fish.

what about a calvis would they go with my other fish cause i really like them and the red terrors. Not sure about the livingston still i dont think 90 gals is big enough for fish that can get 12 in seems kinda small. Thanks for the advice

My kenyi is blue but not sure if shes a female yet cause she only about an inch and a half

your tank is not big enough for a pair of red terrors! They are very agressive andyou nee3d a very big tank to keep them

how can you tell the sex on the red zebras???

For your first cichlid tank try to stock just one type of cichlid (for example you have a red zebra which is a mbuna, so stock with other mbuna species).

As they mature male red zebras will develop a light blue hue to their dorsal fin, additionally they tend to become a orange-pink color (females remain orange). In the wild most male red zebras are actually blue.

thanks so much finally something makes sense

(wish I could go back and edit my comments): you can add 15-25 mbuna in your 90gal. Your livingstoni is a non-mbuna. I wouldn't recommend adding calvus with the fish you have unless you start over and create a tanganyikan set up.

Check your ammonia and nitrite levels periodically, I just saw that your tank has only been set up a week (did you use established filter media and substrate, or is everything brand new?). More advice: add new fish in groups of 4 or more and stock the most aggressive species last.

15-25 fish seems like alot i was thinking more like 8 fish total.Dont really want to over crowd the tank.Do you think i should keep the livingston or get rid of it like i want to.

everything is brand new, how do i check the levels in the tank

he will eat the smaller fish when he gets bigger... I think... I wish I could take him from you, I want one but need to get my fish at a larger size as the fish they get put in with are all bigger! How would you be getting rid of him?

donate him to the pet store i only paid 5 buck for him

Nice, better filtration though. Put a canister filter below.

how big is he? are you near alberta?

hes only about 2 in theres a pic of him if you look in my pics. im in seattle

Whats a canister filter

expensive is what it is, but totally worth it!
too bad you are in seattle otherwise I would take him, I want one!!! but I can always only find babies!(he is very cute btw)

i have two filters both are for a 75gal is that not enough? Like i said im very new at this and seems like everytime i get something it wasnt right.Had no idea it could be some much research.

8 mbuna (if that is what you're going with) in a 90gal is understocked which can result in some higher aggression levels.

In my 100 gallon I have two marineland filters built in. (Their biggest ones) and a Rena's biggest canister filter. Keeps it really clean.

Those filters look like the Aquaclear 300 or 70 filter. (which is the same thing really) and they would probably be ok but it really depends on how many fish you have and how often you will feed them. I have a 60 gal tank and I have two Aquaclear 500's which is one up from those. If you get more than a few fish then yes the more filtration the better. Acanister filter is one that goes below in the stand. An external filter.

Ok your a beginner, and your off to a good start. Filteration is very important. What you have is sufficient. I ran two 30 to 60 gallon filters in my 60 gallon tank, and have had no problem. Canister filters are the best way to go, but can be pricey. Far as fish goes, it depends on what your looking for in your tank. Malawians, tangs, or south american. If you want lots of colors, the go with a Malawi all male tank. Tangs, are cool because they are lest agressive then most. Unless of course you have a breeding pair of brachardi's. It's your tank, all we can do is give you suggestions. Most of us on here a learned by trial and error. It's just the way it goes. I'm sure in time your will become and expert like most. Do alot of research that's what I did. Thank god for the internet. Good luck and remember a healthy cichlid is a happy cichlid.

Almost forgot, get a background black or blue, it will bring out the colors of your fish better.
