Angelfish size requirement?

Hello guys.

I have a 75 gallons waterbox clear 4820 heavy planted 1.5. Years old. 5 gh, 2Kh. 77F temp. I keep siamese algae eaters 6. Rainbowfish. And tetras black neon, and rummy nose. Was wondering if I can add angelfish in there? But people are telling me I need 100g+. But I figured to check with people from different sources. But would a group works or not?

What is the current stocking exactly, i.e. how many fish are currently in the tank?

Tank depth is important to consider for angelfish. I think your tank is deep enough for scalare angelfish, but not deep enough for altum angelfish.

What do you mean by a group? How many were you thinking? Depending on how many fish you have already it might not be advisable to keep many or any.

Your tank is nice. You should clean up that lid though!

I've been following this and other similar forums for a number of years and have never heard that angelfish need a tank that large. I've seen disagreements about whether or not a 29 gallon is large enough (I don't think so, by the way).

One thing to remember is if you buy 2 and you luck out and get a pair they will ferociously claim a section of the tank and attack anything that moves in it. So the more you add, the more potential pairs and combat. I have 3 mated pairs in a 245 gal. At times i may have one pair with eggs or all three! I would say you would be safe with 2 of whatever color you like. I also agree about no Altums due to size.

If it were my tank, I would get a group of 5 or 6 small juveniles and wait for a pair to form then move the rest on to another tank. I would check with your LFS before doing this if you don’t have someone who will take the unpaired ones just to make sure you have somewhere to move them safely.

I have been active in my local aquarium club from time to time and it would typically be very easy to re-home some nice cichlids of basically any kind.

Your tank is very nice congrats.

An old rule of thumb is 10 gallons per adult Angel. So a 29 would be fine for 2, especially a pair. For your 75 I think 5 would be a good number. If two pair up they will keep everyone else to one end of the tank while they spawn. Very rare for them to do actual damage to each other.

A 75 for an angelfish is fine; I think your current stocking is fine with an angel though SAE can get quite large. 6 adult SAE in a 75 is going to be an issue - both in terms of fish per inch; but more so in swimming room and bio film. I don't think people realize just how fast SAE can swim and just how large they get. I intend to keep 4 in a 550 that is 10 feet long.

The only require requirement for an angel is that the tank be at least 18 inches tall (21 or 24 are better) and at least 30 gallons - while larger is always better angels are not super active but if spooked they can move very fast. Females are normally significantly smaller than males and can fit in a smaller aquarium but it does come down to individual fishes as there are small males and large females. This is probably where disagreement in aquarium sizes form. I believe a 29 is large enough for 1 male for a short period of time (3 or 4 months); but way too small for a perm. home; for a female a 29 is plenty large. For breeding a pair it is 'ok' but i would remove them eventually. In my 120 i currently have 5 angels - 2 pairs and a floating something (I think a female but not sure). There is a fair amount of bickering but the stronger female has chosen one side and for this particular female her area is not too large and she is not too vicious (I've had far far worse than her); the other female took me by surprise when i realize she was a female and she is quite passive and lovely. When i move i'll split the two pairs up - one will go in a 550 and the other a 450 - the floater i havent' decided what to do - she or he has been getting pretty beat up recently so i'll figure something out - if i have to i'll move her into a 29 till i move (8 more weeks if i am lucky).

Anyway i'd keep an eye on those SAE; it usually takes 9 to 18 months for them to become adult size (depending on age purchased). While they will keep growing once adults it is much slower and they are not small fishes.

As for number of angels; sex is everything; 5 males will do fine; 5 females might do ok; more than 2 if you have a pair usually fails but it depends on individual fishes. Sexing young angels; dream on. Buy 5 - flip a coin and in 9 to 18 months expect to get rid of 3.

I had 6 dime sized angels in a 55 gal tank to try to get mated pair They did fine at first, but one grew way faster than the others and became a terrible bully. The tank was planted, but not especially dense, and he chased some relentlessly. One jumped out, and he killed another. Once he'd eliminated one, he'd start in on the low man on the totem pole. This confirms what I'd read & been told: they're usually pretty peaceful, but they are cichlids and can get aggressive. So like others have said--keep a close eye and be prepared to immediately remove the bully, or his victims. Your mileage may vary...
