Re: c sterbai dying #1
Thanks Violet.

Maybe it is the Ph. The remaining pair are still around and appear to be ok. I will look into RO supplies again. I might also syphon out the sand. The tank water is about 0.2 more alkaline than tap water which I don't understand.

Cheers,

fs

c sterbai dying #2
would welcome help with this:

set my tank up in June last year - it's a bit over 200 litres with 2 extrnal Ehiem filters.

I stocked in this order after fishelss cycle:
6 red tailed rasbora
5 Corydoras sterbai
3 keyhole cichlid

Over the last 6 weeks I have lost 3 of the 5 Corys, one at a time and weeks between deaths.

The other fish appear fine but the remaining Corys don't look in great shape. They have very slightly bloated bellies and rapid gill movements.

Water:
0 ammonia
0 nitrite
5-10 ppm nitrate
8.2 ph

I know it is hard water for Corys but these are tank bred fish and the supplier kept them in london tapwater pH 8. They seemed fine for the forst 4 months or so.

The substate is sand and I'm wondering if it's gone anaeriobic somewhere? Nothing visible but Ihaven't taken everything out yet. Should I just syphon it all out and replace with gravel? Other problem is algae. It's been quite bad, I've cleaned a lot of it away but there is still brown and green alage gwoing quite profusely. Blue green was growing where the vallis leaves float on the surface so i had to cut them back severely. I don't knwo why there is so mcuh algal growth, I thought iit was just part of the tank maturing but it's been going on quite a few months now.

cheers for any advice.

fs.

Re: keyhole or fairy suitable? #3
Yes, I give them flake, catfish pellets (well obviously these ae supposed to be for the corys but the keholes eat them anyway), tubifix, frozen bloodworm, moaquito larvae, brineshrimp and daphnia. I'd say bloodworm is their favourite.

Anyway, 3 weeks in and a pair has formed, and today I notice eggs on a flat rock beneath a plant. The parents are guarding these quite effectively at the moment so we will see what happens.

The slight trouble is the 3rd kehole is getting a hard time from the two parents - I think I might have to re-home him.

Re: keyhole or fairy suitable? #4
After reading everything I could find on the internet I decided on keyholes. I picked up 3 juveniles today from Wholesale Tropicals. I am very pleased with them at the moment; they are intelligent, energetic fish that have already added something to the tank.

Time will tell if they were the right choice but I am hopeful. Here' two of them. Resized Image

Re: keyhole or fairy suitable? #6
After a bit more research it appears that Keyholes would be the more suitable choice. Does anyone know if these must be kept in pairs or would three be viable?

keyhole or fairy suitable? #7
would either of these work:

I have a 200l approx tank (i think the measured dimensions make it about 240l but obviously sand etc reduces).

I've got hard water, pH just below 8, nitrite and ammonia zero and the tank is fully cycled.

My current occupants are 6 red tailed rasboras and 5 sterbai corys. I am thinking of making the red tailed shoal bigger.

I would like 2-5 larger fish in the tank - would either fairy or keyhole cichilds be suitable?

Other than that I might add an algae eater and possibly a couple of horse faced loaches.

any advice much appreciated.

Re: Help with fishless cycle #8
hammers,

what sort of filter did you get with your set-up? Sounds like it isn't working. I'm doing a fishless cycle right now and got nitrite readings after 7 days.

Also, what is your ammonia source?

Stan

Re: Hard Water Fish - suited to tropical set up #9
excellent - thanks very much for that link. A very worthwhile article and has given me plenty to think about.
