Baby Biorb 15l suitable for goldfish?

lab-lover

Hiya, thinking of getting my dd one of these for her birthday but she wants a "goldfish". Bit confused about these biorbs as ive read they arent suitable for goldfish, obviously big goldfish wouldnt be suitable for this size so i want to know if there are any goldfish or what other type of fish she could put in this size.

If anyone could advise about the baby biorb i would be grateful. thanks. xx

p.s. she doesnt want any minnows as shes had them before.

The standard rule of thumb for small types of fish is 2.5 cm for every 4 liters if the tank has a good filter. Bear in mind though that the fish will grow so you'll need to take this into account, plus any plants or ornaments will take up more room.
