This was beautifully said. Very very important to anyone who is in the hobby to have a similar mindset as this. Respect.If it hasn’t grown in 6 months, its because its not getting enough exercise, has stopped producing somatostatin (growth hormone) and has stunted growth, fatty liver disease, obesity, a whole host of other health issues, and a drastically shortened life span. It just blows my mind that on a forum that focuses on our love of the livestock we keep, people defend what is essentially animal cruelty. The people who do this or defend this practice always say ‘my fish is fat and happy’, not realizing that that is part of why its unethical, your fish shouldn’t be obese. Again, if your tang hasn’t grown in 6 months, there is something wrong
The argument that you can just trade them in is short sighted and irresponsible. Firstly, because it doesn’t always happen, probably not even half the time, people grow attached and because the fishes growth gets stunted they think that they’re not doing any harm and that the tank is still big enough. Secondly, because there just aren’t enough large tanks for all these rehomed (read: disposed of) fish. Over 75% of the hobby is now nano tanks, If there were tanks for all these large rehomed fish to go to, fish rescues wouldn’t exist and every LFS wouldn’t have tanks full of mature fish that don’t sell.
I don’t expect you to rethink keeping a tang in a 50g cube (which is 24”x24”, or about 4” more than a 25g cube), but I hope other people considering doing this, or people new to the hobby will rethink it, it’s really just not cool.
