Nice tank! I'm glad you got the harlequins, they are a nice little fish. I intended to buy 5 harlequins for my 10 gallon to go eith the other fish, but I got sold espe's rasbora, a smaller, rarer version. Yours are definately harlequins. :)
The espei's are cute too! I'm happy for us, Maisy haha. I'm thinking of returning 3 of my harle's and repurchasing them again in 2-3 weeks. Since my tank isn't cycled, I read somewhere that introducing a full school can be detrimental during the cycle, and in the future of the tank in general.
Hahaha I know. They look so much better as a full school. I probably will keep them, and just do water changes every few days. How much and how often do you feed your espei's? I fast my betta every Sunday, sometimes Sunday and Monday. I'm wondering if it's safe to not feed them one/two days out of the week so they can have the same feeding schedule as my current and future betta.
