Hello, I am new and have been reading through and checking the site daily for the last couple weeks.
I went to the lfs today and they had one in stock. They had it labeled as freshwater lion fish. Anyway long story short i decided to buy it and bring it home stick it in my oscar tank for time being, and do some research on properly caring for it. Upon doing my research I have become confused, everyone has diferent info listed on how to care for it as far as fresh/brackish and if it venomous. Any info you guys could find or share with me would be greatly appreciated by me and the little guy.
Also could someone explain this next paragraph to me in plain english. Im a bit slow!
Résumé / Abstract
The nitrogen metabolism and excretion patterns of the grunting toadfish Allenbatrachus grunniens and the effects of salinity on these processes were examined. Individuals of A. grunniens were subjected to several experimental treatments, including variable salinity (2 to 30), high pH (8.5 compared to 7.0 for controls), high environmental ammonia (10mM) and confinement to small water volumes, and measurements were made of activities of selected enzymes of nitrogen metabolism, ammonia and urea excretion rates, and tissue and plasma contents of ammonia, urea and amino acids. Activities of key ornithine-urea cycle enzymes were rather low (e.g. liver carbamoyl phosphate synthetase III activity was 0.001 μmols min-1g-1), and A. grunniens consistently demonstrated a low capacity for urea excretion despite significant elevations of plasma and tissue ammonia contents by the high pH and high ammonia treatments. This species could thus be categorized as ammoniotelic. Total free amino acid contents in plasma and tissues were increased by the high pH and high ammonia treatments, but no patterns were discerned in individual amino acids that would indicate any preferential accumulation (e.g. alanine and glutamine) as has been noted previously in several semi-terrestrial fish species. Thus, it appeared that A. grunniens was not unusual in its patterns of nitrogen metabolism and excretion in comparison to other 'typical' teleosts. Furthermore, manipulation of salinity had no major effects on nitrogen excretion in either this species or in comparative studies with the ureotelic gulf toadfish Opsanus beta. The results are discussed in the context of the broader pattern of nitrogen metabolism and excretion in the Batrachoididae.
