Hi. I have two IT's the largest being close to 9", but it's hard to see for sure. I keep these in a 100 gallon corner tank. Both of them are kinda hiding around for the major part of the day. It was suggested to me to introduce a shoal of other fish to sort of comfort them. I have been asking around what's available at a reasonable size and this resulted in the following species:
- Puntis lateristriga (spanner bard) @ 3-4"
- Puntius everetti (clown barb) @ 4"
- Barbonymus Altus (red-tailed tinfoil barb) @ 4"
