I had two of these given to me recently. They are both around the 9-10 cm mark.
Over the last couple of weeks I have noticed quite a few fish disappearing in the tank, and I blamed the ctenopoma ( that's one huge mouth), but today as I walked past I noticed one of the cats is enormous. he/she looks like he is lying on a beachball.
I did think the cardinals were probably not going to make it, but I've lost tetras, swords, and small corys as well. I had no idea these guys had mouths big enough to try.
think I might have to put this fella on a diet.
Anyone have any experience/ tips with these fish ?
