Generally, i got all my fishes from my country and my aquarium is about 200 gal. Anyway i am not sure about the scientific name of the grunter because i have lost my fish identification book but i can assure you its a grunter. I did not brought him from any aquarium store. In fact i caught him from a mangrove swamp.
Moray eels...huh...it took me along time to look for them all over the aquarium shop. Some marine aquatic stores do have them in their marine tanks although the morays are estuarine. The moray i meant is gymnothorax tile. For the gymnothorax polyuranodon, i was sooooo lucky to find it from a freshwater fish dealer. :P .
Chelonodon patoca is quite commonly available but still it is considered quite rare because it is normally found mixed up with green spotted puffers. In a dealer's tank full of green spotted puffers, there will only be 5-8 milk spotted puffers. The flower horns craze are really making my findings difficult.
