has the flowerhorn always been in the same tank with the other fish...?
i love flowerhorn, but as they get older they start killing everything else in the tank... unless it's a female...
nice Tetraodon lineatus... i had a couple of those once... they get pretty large and are aggresive eaters... you know that that fish gets over a foot long... 20" to be esact... and if something fits in thier mouth it's going to be food...
oh and guys... a tetraodon lineatus is called a fahaka puffer at the petshops...
Heh. There's no hope for inverts with that fellow lounging around. Crawfish = dead as soon as it hits the water. I've watched a good number of those large fahakas on youtube. He's not in your 46gal though?
