I was doing my monthly maintence on my fluval 204 filter today and found a bunch of weather laoch babies .... alive !! they are alittle over an inch long and FAT. only one survived being moved to a new CLEAN home but he seems happy and is huge compared to the 2 that never made it into the filter .has anyone else ever had this happen before? is feeding fish food ok or do they need something else (the 2 small ones have been surviving off fish food but now I think there is something better because the one is sooo much bigger )
