Mosquito fish (Heterandria formosa) are the best, after corydoras of course. Other than Cories they are the only fish I have and i have them everywhere. I think mainly because I am jealous of the males. Check them out.

I have a range of different sized tanks and I go by the bigger the more stable so my regime is as follows

400l once a week 25%
120l twice a week 20 %
95 l every two days 10%
50 l breeding tanks every day 10% unless cycling for season mimicing.

I wont mention the egg and fry tanks which are 50 ...

Depend alot on what cichlids you are refering to. There are many options but they will depend alot on the cochlids. Sth american , african, dwarf?? Can we have a little more info please

money has clouded you judgement and your ethics. maybe you should have remained as a hobbyist. I am fully aware community and breeding tank is different. I have a good number of both and the fish interchange between them. Water quality, care and good husbandry has meant that thus far the fish have ...

I have a very simple question for you... all I really want to know is WHY do you keep fish. Can you give me the honest answer.
As for your sodalis, I have half a mind to take them, at least they would be safe. I have a 400l tank with room that I am sure that would settle fine in.

Fortunately I dont know how to quote and also I have respect for the ppl that run this fantastic forum so I wont say what I want to. If you are disgusted at a species due to the fact that you are inept and unalbe to breed them get over it. You arent a fish keeper you are a man that has fish and ...

The dorsal fin doesnt look big enough for the C3 also the black banding isnt very prominant across the eyes. I would suggest young axelrodi, they are quite variable in colouration anyway. Loxozonas juveniles are a possibility also, how big are they and do you have any idea of their origin?

The rena tank that you are sp[eaking of is currently £880 in most maidenhead aquatics and it comes with all lighting and filtration.

aeneus type. To me it looks like one of my aneaus, There is so much colour variation within the aeneus group. I agree that although the yellow on the fins it isnt a melanotaenia. Sorry if this isnt what you were hoping and I maybe wrong .

cartouche, maybe I am wrong but you started this thread to ask about the priciple of hormonal breeding in corydoras and the response is pretty categorical. NO, its a poor idea. Youe apparent need to justify it use brings into question your motives for starting this thread. As far as I am concerned ...

Can I ask which woods people consider to be safe for tank use I appreciate the boyancy issues but I am more concerned with the alakloid and toxicity side of their use.
Thanks in advance

I am with Kim on this one, you describe your fish keeping like a business. Some fish are easier thasn others to spawn and thats life. If you dont like the species because of their difficulty to breed then keep the others. As for the wasted time and money along with fish deaths that you mention.. it ...

I would like to support barbies comments regarding fish comming out of uv water. Whenever we get fish from the wholesalers that run uv filtered systems we expect the initial influx of whitespot and bacterial infections which result the reduced immune systems of the fish. UV appears to be too ...

I am interested in opinions on hardness of water. Which would people feel is best to test for. TDS, KH or GH readings I accept that they are all integrally related but wanted some opinions. I am leaning towards TDS as a one size fits all indication of hardness.

Thanks for that, How big is the tank and how is it decorated.? Sorry for being nosey?

These came in as C57 but I am not convinced that they aren't microcanthus. Let me know what you think

I have read alot of literaturew that suggests that male barbatus fight and so should be kept apart. Is this also the case with the females. I have a gorup of 4 youngsters ( 1 male and three females ) about 2.5 inches. I have even had them spawn twice but the tank is not set up for breeding and I ...

What was he in with, to me it looks like something has nipped the tail fins, no sign of fungus or rot. Also the one that passes away looked emaciated. Is enough food getting to the bottom. Smaller cories find bloodworm hard work. Try tubifex or best of all for the small ones tabimin. Hope this helps

They are in five litre galss containers Heated to 74 and with vigorous aeration. They are water changed three times daily with 50% changes. The paleatus, aeneus and even pygmaeus have been fine this way but the napoensis are suffering. Its like the gills fill with the stuff. The ones that are ...

Maybe fibrous is wrong, i guess mucousy ( if thats a word) is more accurate. Either way it is clogging up the tiny fry. The larger aeneus and paleatus appear unaffected , even the bigger napoensis appear to be do ok. I syphoning the worse of it and doing so twice a day during the water changes but ...

I am having a problem in my fry containers. There is an accumulation of what i can only describe as slime. It is quite fibrous and the fry are appearing to choke on it. I am convinced it is bacterial blooms. I am, as describe doing 2 50% water changes a day and have a good air supply maintaining ...

I have used peat as a substarte once when about 15 years ago. I used for breeding small characins. I used the pure peat from the garden center, the hard part was preparing it for the aquarium which took about two months. If used in a filter it doesnt matter whether it sinks or floats as you are ...

I have just been doing my daily routine of water changes and when I got to the barbatus groing tank whcih hold 4 young barbatus 3 female and a male ( 2 inches max) I have found three patches of eggs. a group of 8, 6 and 3 They are beige in colour and have a slightly darker centre. I have various ...

I have considered rain water but this is london rain and not known for its cleanliness. Should I be worried or not?

I run 10 tanks with the main focus on keeping and breeding Corydoras, I want to start softening the water as muy tap parameters are like lake malawi ( literally) I have had no problems keeping the cories and even breeding a few of the easier species and all is going well. I now want to get more into ...

Any chance of a photo of the eupterus, I agree none of the tank mates would have done that. I does as mark says point towards disease. The actual disease and the extent of the damage is key to whether it will recover.

Thanks for the reply, I am glad its not just me. This group including the brevirostris all look so similar.

Before I went cory crazy , i kept and bred malawi cichlids. I had some fuelleborni fry which I had taken from the female. I introduced all into the fry tank and left the net on the tank hood. The next day ( about 36 hours later) i used the net again and a yound week old fuelleborni swam out as happy ...

I always prefer 2 smaller heatersw toward the one. The reasons are two fold. If the thermostat sticks on you have twice the time to detect the problem before you lose all your fish ( I learnt this the hard way.) Also if one breaks the second can maintain temp for you. Another reason is you will get ...

I appologise if this is an easy one but I am awful at distinguishing between some of these cory species specifically schwartsi, melanistus, delphax, ephippifer.
I think these are melanistus but would like a second opinion

Thanks
