[tropicalwaters]

Just out of curiosity, whats the most challenging fish you have kept?
Mine: lungfish

 

[GuppyDude]

Presently, my oscar.
He's gone a bit gangster recently, killed his partner last week and is swimming around with a crayfish tail sticking out of his mouth this morning.
Hope he can cough it up, cos it's going to hurt him.

mine would habe to my african cichlids

Chocolate Gourami's, gonna try em again soon tho a few months down the line.

 

[CFC]

Paradise threadfins (Polynemus species) i failed miserably both times

 

[dthoffsett]

Dwarf gouramis, I finally gave up on keeping them, every one of them I get dies of bloat. I'm not sure if it's something I've done or just the supplier getting bad stock.

 

[freshwaterfishlover]

Harliguen Rasboras. I bought 10 and they are all starting to die. Now down to 7. When they all die I will not buy anymore.

 

[benniebru]

german rams for some reason when i had them i could not keep them alive they would be fine one day and dead the next so i moved on to different fish

 

[PRW1988]

lol probably neon tetras... I don't know why, I just have no luck with them, they'll be fine the first week or so, but after that the start to die I've bought 10 before and after 1 month I was left with 2

 

[majik]

mine would haf to b seahorse babies i had seahorses for years and they did really well but would forever have babies very few actually survived

 

[nurglespuss]

weather loaches.

Everyone I've ever had has eventually found a way to escape.

 

[tucan]

swordtails - somehow they never seen to survive more than 4 weeks. oh and african chihlids. i can't tanks mates that they won't kill.. if there is no one else around, then they start to kill each other

 

[smithrc]

Otocinclus affinis (ottos)..

Didnt matter what I tried - they just don't like my tanks...

 

[luque]

have to agree with tucan, i gave up trying to keep swordtails, just kept dying, don't know why
