Need advice

[Jason20679]

Hi,

I had in my tank (rio 180) 1 x L229,1 x Cardinal Tetra, 3 x Clown Loach, 5 x Apistogrammas, 6 x Rosy Tetra and 19 x Green Neon Tetra.

The tank has been running since end of Feb using fishless cycle and all was ok until this last week.

I added 3 male Guppies and 3 Otocinclus on Fri 13th. By sat night 1 Guppy was dead but it had disappeared before i could take it out.
Monday a 2nd was died and a rosy was missing. Wednesday the last Guppy died and a Green Neon but the guppy went missing before i could take it out.
I took out most of the features in the tank and counted all the fish.
Out of the 19 Green Neons i counted 17, 1 i took out so 1 is missing. I now have 4 Rosy out of 6, 1 i took out and 1 missing and there's a Guppy in there somewhere.

Where could these fish be?
and
What should i do, big water changes (50%) every other day or little water changes (10%) everyday?
or is there anything else i can do?

Thanks

J

Have you checked all water perameters? If you have and all is well there are a few possibilitys.
1...The clown loaches could be having a meal on the sml neons and guppys, but I wouldn't have thought they would do that to rosey barbs.
2...You added fish that were not ready to be sold and they have columnaris which is very nasty and can go through your fish very quickly...Do you see anything strange with the dead fish that you can see? or on any of the remaining ones?.
The reason you are not finding bodys will be down to the clown loaches and others cleaning up.

The problem seem to start on Fri 13th, of all days, when i added the Guppies. Their tail fins started losing colour and it spread up their body till they died.
I've managed to get 2 of the 3 out but i can't find the other.

I had an idea that the Clown Loach might be eating them, after they died, but 1, The Clown Loach are only 5cm and 2, there doesn't seem to be any remains.

I'm gonna start some small water changes when i get in from work.

As above plus you need to make sure the parameters are correct for any fish you buy and also it is always a good idea to try and find out the water parameters from where you bought them from before adding to your tank. Less hardy types are likely to suffer with big changes.

Also you should really invest in a quarantine tank, introducing sick fish to a community tank could lead to you having no fish

Also forgot to say, most otos need a well established tank and pref some plants, i seriously wouldn't consider having these until your tank has been running for at least 6 months, thats just my opinion though.

That is fin and tail rot the guppys have and is very nasty...Give the aquarium a good waterchange then add a teaspoon/5ml of salt per gallon and something Like Esha 2000...Remember if you have soft water you have to double the dose of Esha 2000.
