Hi all, Im looking for a cory for my tank 20 H with large angels and not much else in it . Would these corys be good in it ? Is 10 a good number ? My PH is 7.6 and 80 temp. in te tank. Im trying to breed the angels , would the cories eat the eggs ? Any info would help, also theswe would be wild caught fish------

C. habrosus are OK at temperatures up to about 79'F, so should tolerate 80'F OK.

They will probably eat the eggs if the parents aren't watching them, but generally, Angels will guard the eggs sufficently that it's not a problem.

Not that angels are catfish, but to breed them you would better lower your pH.

Personally I would do thet by using (more) wood in the tank, especially wood ripened in peat. You could also try to find what makes your pH high, such as chalk containing rocks or sand

I suspect Arizona water is to blame, just like the water in Southern England is quite hard and high pH.

I didn't find any good source of information as such, but this page indicates hard water, which usually also means higher pH levels:

If you are trying to breed the angels I believe 10 corys in a 20 gallon would be a major distraction.As far as breeding them you failed to mention if you check your waters TDS. A tds around around 80 and a temp of 80 should produce the results you want.

Whilst soft and low pH water may be ideal for Angels, I would say that it's probably not necessary - one of the managers at my favourite LFS breeds Angels, and I'm pretty sure that's in the basic local water, not RO water. Our water comes out of the tap with pH around 7.5-8.

Hi guys thanks for the replys, Im not going to put them in with the angels, I might start a 10 gallon tank for them My angels are large and I want to focus on them so thanks for the great advice, now if I knew if they were a male and female ? Well time will tell !

Vinnie,
Are you saying that you are trying to breed a pair of wild angels? If so, then you should use soft acid water. I am assuming they are P. scalare. Visit www.finarama.com for much information about breeding wild angels.

Corydoras habrosus would suffer if kept with a mated pair of angels. Some may even be killed.
I regularly breed Corydoras habrosus. One of the easiest ways to breed them is to fill a five gal tank with Ceratophyllum submersum supplied with a sponge filter. I would try 76*F for their spawning tank. Leave the breeders in the tank seven days then remove them. Corydoras habrosus fry will begin appearing on the 5TH or 6TH days and then more each day for about a week after the last day the breeders were removed. Then remove much of the Ceratophyllum and be careful to shake it out as you gradually remove the excess plants. Leave some plants, it helps the fry if they can easily hide and the additional surfaces of the plants help provide some of their first microscopic foods.
I use chilled bbs rather than microworms as their first, then primary food. It is also useful in conditioning the breeders but I would also feed black worms.

C. habrosus tend to lay large eggs for their size but not very many compared to the larger Corys. Still, I would expect 25 to 50 fry depending on how many breeders you used. Males tend to be no more than 2/3 the size of the females and females are broader at the the pectoral fins than the more streamlined males. Two males per female is a good ratio.

easy, the one laying the eggs is female, and if they hatch, the other is male

This may sound rather obvious, but angels are notorious hard to sex - and for 2 females depositing eggs together without any male. Therefore, prepare to spend quite a lot of time in front of the tank

Hi guys, no Larry they are regular fish, no the Habrosus would be wild , I found a place in florida Floridaguppies, Luis is a great guy so I may buy them from him. Im looking to sell my angels , my tank is 20 H and these guys have extra long fins and need a large tank !
